Direct Link To This Post Topic: An Illustrated Guide to Prog Rock Instruments (new
    Posted: June 29 2014 at 16:06


In this article I am reviewing some of the most relevant instruments frequently used in Prog Rock from an historical point of view, especially focusing in those more widely used in the classic Prog Rock period of the 1970’s, although I have also included some more modern interesting instruments.

For sure a more precise title for this article should be something like “An illustrated guide to some of the instruments frequently used in classic Prog Rock”, since the list does not intend to be comprehensive and all these instruments were of course not “Prog Rock instruments”, they were simply instruments of their period, used in Prog as well as in many other genres during that period, but the title is intended as a practical shortcut.

Most references are made generically (e.g. ‘the Hammond Organ’) but I have also included some particular instrument pieces owned and played by famous Prog musicians (e.g. ‘Chris Squire’s Wal Triple-Neck Bass’).

Traditional instruments like guitars, basses, drums or flutes were nothing new when Prog flourished and have seen limited innovation right up to the present. The development of the synthesizer on the other hand went very much in parallel with the development of Prog Rock itself, for this reason the keyboards and synths are covered with greater historical detail, while entries for traditional instruments such as guitars, basses, flutes etc are limited to a few general comments.

The history of synths is only covered until the rise of digital synths in the early 1980’s, after that the number of different manufacturers and models would become prohibitively long. Moreover, in modern times (since the advent of MIDI in 1983) the keyboard model we see being played by a certain musician does not always tell much, frequently they are used only as controllers and the actual synthesizers or sound patches are located in racks or audio workstations.



When asked about quintessential Prog Rock instruments many will think of the Mellotron, but no reference to the ‘Tron’ would be fair without mentioning its direct precursor the Chamberlin, since the Mellotron was born essentially as an illegal copy of the Chamberlin.

Developed from 1948 onwards by Henry Chamberlin in the US, this keyboard was the first sampler (more precisely the first Rompler since it could only play back sounds, not record them): pressing the keys triggered playback of pre-recorded tapes with recordings of real instruments. The sounds included assorted keyboards, bowed and plucked strings, winds, voices etc (and in some models rhythms loops). For the first time it allowed producing realistic orchestral and vocal sounds from a keyboard. On the model 600, the blueprint for the first Mellotron, each note tape had a maximum duration of 8 seconds and returned to its starting position when the key was released or when reaching the end. 

It was originally designed as a home instrument, not portable (until the release of the M1 model in 1970) which made them delicate and not suitable for Rock bands outside of the studio. The M1 model released in 1970 was compact and portable (even more than the Mellotron M400) but by then the Mellotron had taken over (see the Mellotron entry) and the Chamberlin has unfairly remained rather obscure and unrecognised compared to the Mellotron. Many consider the sound samples of the Chamberlin to be of superior quality than those of the Mellotron.


The 1951 model 200 was the first melodic Chamberlin (the first model 100 from 1948 played only rhythm loops)

Chamberlin 600 1962, the blueprint for the first Mellotron

Chamberlin M1


 In 1962 a sales employee of Chamberlin Bill Fransen fled to Europe with two Chamberlin 600’s and without Henry Chamberlin’s knowledge he claimed that the instrument was his invention and made a deal with the Bradley brothers from the UK to build upon the design and manufacture the machines. So although the Bradleys introduced some modifications, the Mellotron Mark I was born in 1963 essentially as an illegal copy of the Chamberlin 600, the 3 violin samples were even the same from the Chamberlin (the other instruments were newly recorded).

 Mellotron Mark I

When Henry Chamberlin and the Bradleys realised the situation they discussed and eventually reached an agreement by which Chamberlin would receive some royalties for the original design and for some period Chamberlins would be sold in the US and Mellotrons would be sold in Europe. In retrospect Mr. Chamberlin probably regretted this point, the Pop and Progressive music scene during the 2nd half of the 1960’s was more innovative in Europe than in the US so by the time the instrument really kicked in during the late 1960’s it was the Mellotron and not the Chamberlin which got the limelight, and by its heyday in the 1970’s few people remembered the Chamberlin at all.

Already in 1964 the Mk II was released which was nearly the same as the Mark I just with a few improvements. In fact most Mark I's were upgraded to Mk II specs.

There is a bit of a mess with the different companies involved in producing and selling Mellotrons so to clarify things a bit let's start by saying that the Bradleys original company was called Bradmatic but for the Mellotron business they soon established 2 new companies, the sales and distribution arm was called Mellotronics and the manufacturing arm was called Streetly Electronics. 

Around 1965 Mike Pinder from The Moody Blues worked at Streetly for 18 months as a quality controller and test-player, and he fell in love with the instrument and eventually got himself a Mk II. He introduced the Mellotron to The Beatles who quickly purchased two of them. They used it in Strawberry Fields Forever released in February 1967 and Pinder himself used it extensively in Days Of Future Past released later the same year, and this launched the popularity of the Mellotron in the Pop-Rock music scene. Around one year and a half later the use of the Mellotron by King Crimson in their seminal In The Court Of The Crimson King situated the Tron as a paradigm for the Symphonic Prog sound of the 1970's..

As with the Chamberlin, the first Mellotrons were not designed to be portable (although the 1968 M300 was more compact than the Mk II), but this changed with the release of the M400 model in 1970, by far the most popular and widely used in Prog Rock. Due to its smaller size it could only use 3 different instrument tape sets at a time but it compensated by having the tapes in cartridges (referred to as 'tape frames') which could be replaced rather quickly. EMI also produced 100 units of the M400 under license, named M400S, reportedly of lower quality.

Mellotron M300

Mellotron M400, the archetypal Prog Rock Tron

Due to the tapes playback system (of 8 seconds duration like the Chamberlin) which had to return to their starting position before being able to be played again, they had a slow action not making them suitable for fast playing and the notes did not decay naturally when the key was released, but they were great for slow passages of sustained sounds such as strings, choirs, brass or flutes which were difficult to mimic by synthesizers of the time (besides their big advantage of being polyphonic versus their contemporary synthesizers).

Mellotrons are infamous for being very sensitive and unreliable, the tapes often jammed, the motors and mechanics did not work properly etc. Musicians on tour frequently decided to take two of them in order to have a backup and they had to be repaired in between gigs. Rick Wakeman was so pissed off with their unreliability that when he could start using more advanced instruments such as the RMI Keyboard Computer and the Birotron prototype, he took two of his Mellotrons to a field and set them on fire.

A picture of one of the very few occasions in which ELP used a Mellotron live (an M400, here topped by a Minimoog). It was played by Greg Lake in the Trilogy tour for Abaddon’s Bolero but they used also some pre-recorded tapes and a click-track for Palmer on his headphones, and they had many problems with the synchronisation and reliability of the whole set-up and after a couple of gigs they decided to drop the song from the set list. Emerson never liked the Mellotron, because of its unreliability and because you could not play fast with it.

In 1975 the Mk V was released which was basically two M400's put together in a single cabinet. The development of the Mk V was possibly inspired by the custom instrument assembled by Rick Wakeman, who had put two M400’s together in a single cabinet in order to have 6 different sounds available at once. Wakeman's double M400 got stolen but it was recently recovered by a guy in the US who plans to restore it, Wakeman told him that he could keep it.

Rick Wakeman circa 1974. On his left we can see his custom double Mellotron M400 topped by two Minimoogs.

Notice that this instrument had the knobs on the top like the M400 while the genuine Mk V had them below the manuals. In front of Rick the Hammond C-3 organ topped by an RMI Electra-Piano and a Hohner Clavinet C6. On his right a piano topped by an Elka ElkaPiano 88 and a third Minimoog. Behind him stands the keyboard of his portable Mander pipe organ (see the Pipe Organ entry).

Around 1976 there were some legal disputes regarding the name Mellotron, which had been licensed to the US distributor DMI (Dallas Musical Instruments) which went quickly bankrupt and was then re-established as Sound Sales (retaining the Mellotron name licence and also referred to as “Mellotron USA”) to continue producing and selling Mellotrons.

Streetly continued also producing Mellotrons but had to sell them under the name Novatron. In 1981 Streetly released the rare Novatron T550 which was packed in a flight case for touring convenience, but only 4 of them were made.

Novatron T550

From their side Sound Sales developed the also very rare Mellotron 4-Track which could play the 4 tracks simultaneously (each track with independent EQ, panning and mix volume), of which only 4 units were produced in 1981 (to add to the names mess, the manufacturing company of the 4-Track was Bomar Fabricators).


Sound Sales Mellotron 4-Track

In the mid-late 1970’s the development of more advanced instruments such as the polyphonic string machines, the RMI Keyboard Computer and the polyphonic synthesizers (see the Polyphonic Synthesizers entry), and the development of digital technology including sampling with the Synclavier and Fairlight caused a quick fade out of the mechanical Mellotron, which suddenly felt like an ancient machine. The revival of Prog in the 1990’s renewed the interest in the Mellotron but before that, in the late 1980's the rights for the name Mellotron were acquired by an American guy called Dave Kean.

A Swedish guy called Marcus Resch who was repairing Mellotrons for bands like Anglagard and Anekdoten teamed with Dave Kean in the 1990's to start producing Mellotron service parts, and as from 2001 with the benefit of owning the name Mellotron they released new and improved analog replicas of the M400 (which they called Mk VI) and of the Mk V (which they called Mk VII). From 2010 they also produce a digital model the Mellotron M4000D.

The German Manikin’s Memotron is another popular digital replica and of course sample patches are available in other keyboards or for uploading to workstations.

A son of one of the original Bradley brothers from his side restarted Streetly in the 1990's to repair and restore Mellotrons, and in 2007 Streetly released a completely new model, the M4000, analog but with a completely redesigned tapes system which allows 24 sounds in the machine at once, eliminating the need for removable cartridges. This was not marketed as Novatron but simply as 'M4000 by Streetly Electronics'.

Some archetypal uses of the Mellotron (aka ‘the Tron’) can be heard in the intro to Genesis Watcher Of The Skies, the choirs in King Crimson’s Epitaph or In The Court Of The Crimson King, or the flute in Led Zeppelin’s Stairway To Heaven.



The brief existence of the Birotron is anecdotical but worth mentioning due to the involvement of Rick Wakeman and to its extreme rarity. It was developed by Dave Biro in late 1974 as an attempt to solve the Mellotron’s weak points, and on paper it delivered. Instead of tapes of 8 seconds duration the Birotron used closed tape loops which could hold the sound indefinitely, this gave it also a much quicker action allowing playing of faster phrases (according to Wakeman you could play it “as fast as you like” which coming from him is quite something), it had note attack and decay settings (basically a must requirement when operating with closed tape loops without any attack or decay by themselves) and a pitch shifter knob. Regarding reliability nobody knows, it disappeared before anyone could tell.

Rick Wakeman was so impressed by the concept that he decided to co-fund the project, some prototype machines were built and advertisement started in 1976, and the company Birotronics received over 1000 orders from customers like Keith Emerson, Elton John, John Paul Jones or Patrick Moraz. Unfortunately issues during late pre-mass-production development to ensure high quality and reliability, plus the need to record all the samples with real musicians resulted in increasingly high costs and Rick Wakeman’s finances were going through a deep period, and at the same time advanced polyphonic synthesizers and digital technology were progressing fast, leaving a mechanical tapes machine outdated, and the project was finally aborted.

It is unknown how many were built precisely, according to some accounts only 17 complete machines were built and only 2 survive today, which has earned the Birotron the title of rarest modern musical instrument.

It was used by Wakeman in the album ‘Tormato’ and the YesShows tour, and although he owned up to 4 of them he does not have one anymore.

Tangerine Dream, who were known for modifying or custom-building much of their equipment, were one of the very few to get their ordered Birotron, although before that Chris Franke had already modified one of his Mellotrons to have it work with loop tapes (credited as “Loop Mellotron” in their 1976 album Stratosfear).

Tangerine Dream’s Edgar Froese in his home studio in 1979: at the bottom left of the picture we see the Birotron, topped by a Korg PE-2000 string machine (itself topped by a Roland Micro-Composer MC-8 sequencer) and on their top an Oberheim 4-voice synth. Behind Froese a custom modular Moog with a Korg Vocoder on top of the modules cabinet. On top of the Moog controller keyboard there is an ARP Pro/DGX (an evolution of the Pro-Soloist). At the right of the picture a Fender Rhodes topped by a Solina String Ensemble, a Hohner Clavinet and an Elka Rhapsody 610. On the stool a Gibson Les Paul guitar.



An iconic keyboard like few others, the Hammond Organ was invented by Laurens Hammond in 1934 as an affordable alternative to pipe organs in churches and upright pianos in middle class family homes. As such it is not just a prominent instrument in Rock music, it has had massive presence in nearly every style of popular music since the late 1930’s, gospel, blues, jazz, soul, pop, prog or hard rock. It generated the notes by mechanical tonewheels rotating in front of an electromagnetic pickup. The mix of the different harmonic components could be altered in real time by its famous drawbars providing a very rich range of possible organ timbres, from soft church-like sounds to aggressive and fierce Hard Rock tones. This versatility surely contributed to its huge success in such a wide range of music styles (mathematically the drawbars provide around 235,000,000 possible different sound combinations). The Percussion function provided a very distinctive percussive attack to the sound, which can be clearly noticed for example in many parts of ELP's Tarkus. 

A very frequent companion to the Hammond was the Leslie Speaker cabinet, which amplified and released the sound via two rotating speakers. The rotation produces an oscilating doppler effect which creates a very unique sound, like a combination of vibrato, tremolo and phaser effects all in one.

In the times when bands still had to play without PA systems, the Hammond with Leslie was the first organ powerful enough to allow keyboardists to play live alongside rock electric guitarists without having to feel ‘in the background’.

Many different models have been built but from a Prog Rock perspective the console B-3 and C-3 and the simpler spinet L-100 were probably the most widely used (Tony Banks used a T-102 which was a model very similar to the L-100 but working with transistors instead of vacuum tubes). Technically the B-3 and C-3 were basically the same, the B-3 had an open lower section with 4 legs while the C-3’s cabinet was closed at the front and sides.

Virtually every respectable keyboardist in the 1970’s Prog Rock scene had a Hammond, but we may mention Jon Lord and Keith Emerson as particularly notable users. Keith Emerson’s live performances stabbing knives on his L-100 to hold the sustain or playing it upside-down from the floor became iconic (although his regular playing was done on a C-3 placed below the Modular Moog).

Robert (Bob) Moog was the most prominent pioneer in the development of the modern analog synthesizers utilized in Rock music.

The precise division between ‘Electric or Electronic Organ’ and ‘Synthesizer’ (if there should be any at all) is controversial with early devices such as the Telharmonium, the Trautonium or the Ondes Martenot dividing opinions, but often the first really fully-functional musical synthesizer is considered to be the vacuum-tube Hammond Novachord from 1939 (which incidentally was fully polyphonic!) but it was way too ahead of its time, very complex and costly, and WW2 quickly interrupted its production before people could really understand it, and it remained mostly used to generate eerie sounds for movies and TV shows rather than actual music. If you have watched classic sci-fi movies from the 1940's and 1950's, chances are you have listened to a Novachord generating the sounds of flying saucers or energy rays. 


Hammond Novachord

The Buchla synthesizers from the early 1960’s also predated the Moogs but they were also oriented to universities or the cinema, TV and electronic music industry rather than to live performing musicians (one of their characteristic features was a touch-plate keyboard instead of a real musical keyboard).


Buchla 100 1963

Touch-Plate Keyboard in a Buchla

Robert Moog on the other hand set out to develop the synthesizer for actual performing musicians. Based on ideas first proposed by Harold Bode and the work of Buchla, in the mid 1960’s he further developed the technology of voltage-controlled sound synthesis based on transistors (compared to previous vacuum-tube technologies like in the Novachord) and a sort of road-map for standardising sound electric signals manipulation using voltage changes as the controlling mechanism. So for example, he devised how to generate a basic sound wave from a voltage-controlled oscillator, but also a systematic method for modifying that original signal through subsequent ‘modules’ before releasing it to the amp and speakers. So the original signal could be processed through different modules such as signal amplifiers, envelope generator, filters, modulators etc until it got the final shape. The modern musical analog modular synthesizer was born, with his first complete operating machine being ready in 1964.

The instrument received a lot of exposure when Wendy Carlos recorded the album Switched On Bach in 1968, a selection of JS Bach pieces played entirely on Moog synth (which considering that the synth was monophonic represented an impressive work of overdubbing).

Keith Emerson had also been closely following the Moog development and cooperated with Robert Moog in improving the instrument and popularized the new synth from his band The Nice and later on ELP, being the first to take one in live rock concerts.

The Modular Moog was not a definite machine but rather a flexible concept, frequently custom assembled with different modules according to each musician’s desires so each unit might look bigger or smaller or slightly different. Originally there were two main choices for the cabinet structure, the C series cabinets were more horizontally laid and intended more for static operation such as in studios, while the P series were based on more rather squared cabinets more suited to portable use. Keith Emerson's famous rig was based on a 3C unit while other performers such as Tangerine Dream or Klaus Schulze opted for the P units. It’s also important to realise that the Moog Modular was not ‘a keyboard’ but rather a sound generator-processor system. The musical keyboard was the most convenient user interface to provide input to the system, but other interfaces could be used such as the ribbon controller famously used by Keith Emerson and first seen by many of us in the video of Pictures At An Exhibition (these considerations apply to many other synthesizers as well).

The different modules had to be connected with patch cables which provided a powerful visual sense of huge complexity. Keith Emerson’s Moog array even included a CRT oscilloscope.


Keith Emerson’s Modular Moog 3C array (on top of his Hammond C-3 organ)

Even in more modern times the paraphernalia of the patch cables continues providing visual effect, even if possibly his patches are now programmed.

The Moog Modular was monophonic, in 1975 Moog released the Polymoog as their polyphonic synth alternative.

Moog also conceived a 3-piece Synth Ensemble which they called “The Constellation” consisting of a polyphonic synth called Apollo (which would become the Polymoog), a monophonic solo synth called Lyra (basically a bigger and upgraded Minimoog, some of which technology would be used in the 1978 Multimoog) and a foot pedals bass synth called Taurus (which would become the famous Taurus bass pedals). The Apollo and Lyra prototypes were played by Keith Emerson in the Brain Salad Surgery album and the 1973-1974 ELP tour including the famous California Jam gig but the Constellation Ensemble was never actually marketed, yet it paved the way to two important new instruments the Polymoog and the Taurus bass pedals.

Other notable users of the Modular Moog were Tangerine Dream, Klaus Schulze or Tomita, and more recently Erik Norlander (Rocket Scientists, Lana Lane, Asia featuring John Payne and solo) has also regularly used a Moog Modular.

Tangerine Dream's Chris Franke in 1975. Behind him the modular Moog (P series cabinets), in front of him an Elka Rhapsody 610 on top of a Mellotron M400, and on the top right of the picture we see (not completely) an EMS Synthi A.

Perhaps ironically, in some sense the bold Constellation Ensemble concept foreshadowed the demise of the original Moog Music Company, since what it proposed was actually never delivered by them but by another manufacturer. By that time Bob Moog was getting himself distanced from the company’s product development, the Constellation was not brought into production and instead it was Yamaha who released a similar instrument, the GX-1 in 1975 (see the polyphonic synthesizers entry), which while having limited polyphony, not having the modular structure of the Constellation and being very expensive produced a great, very fat and full synth sound.

On the other hand the Apollo / Polymoog, the polyphonic synth module which had to be the true technological innovation of the Constellation Ensemble leading to high expectations (with most people expecting some sort of polyphonic Minimoog) failed to deliver in many aspects. Its development was not led by Bob Moog but by David Luce, and in seeking for full polyphony he opted for the divide-down technology associated with string machines (see the ARP Synthesizers entry), which could not produce the fat sounds of the Modular Moog or the Minimoog. The resulting Polymoog (see the polyphonic synths entry), while having many good features had rather thin sounds and limited programmability, it suffered from disastrous unreliability (a 200% failure rate) and it frustrated many musicians who had been expecting the usual Moog sounds in polyphonic mode.

Yamaha on the other hand quickly adapted the technology of the very expensive GX-1 into a more affordable polysynth, the 1976 CS-80 (see the Polyphonic Synthesizers entry), which while again being only 8-voice polyphonic had a great full sound and was reliable. And soon after in 1978 Sequential Circuits released their iconic 5-voice polyphonic Prophet 5 which besides great sound and programmability also included good memory storage for user-programmed sounds. In comparison Moog remained rather still, in 1978 they released a stripped-down, mostly-preset version called the Polymoog Keyboard (280a model) which did not add anything in terms of performance, so again it was actually Yamaha and Sequential Circuits who delivered what people had expected from the Moog Apollo / Polymoog, a high performance and reliable polyphonic synthesizer.

In the meantime Bob Moog had left his company in 1977 (which was acquired by Norlin) and it took them until 1982 to release a proper rival to the CS-80 and Prophet 5, the Memorymoog, which by limiting polyphony to 6 voices achieved finally a nice full synth sound with good programmability (although puzzlingly for its time it still lacked a velocity-sensitive keyboard, which the Polymoog did have). Much too late with the digital Yamaha DX-7 about to hit the streets. Moog had fallen very far behind the competition, they still presented the SL-8 digital-analogue hybrid prototype in 1983 which looked quite promising, but the iconic DX-7 and its followers quickly sent analogue synths to oblivion for the next decade. The SL-8 never reached production and Moog Music finally closed by bankruptcy in 1993, but Bob Moog eventually recovered the rights for the Moog name and re-launched the company in 2002 (see the Minimoog entry).

The Moog Modular synths were big, expensive and cumbersome with all their patch cables, so in 1970 Moog released a compact monophonic synth which was affordable and could be used for great soloing, the Minimoog D (the models A to C were pre-production prototypes). It was a revolution and it became a paradigm for Prog Rock, allowing keyboard players to rival guitar solos from a compact device. It was small enough that it could be conveniently placed on top of other larger flat-top keyboards (it fitted nicely on top of a Mellotron or a piano), and it offered amazing crisp tones suitable for aggressive soloing. Many of the synth solo lines heard in quintessential 1970’s Prog Rock albums were played on a Minimoog, Rick Wakeman and Keith Emerson being archetypal Minimoog users.

The Minimoog was also the first synth to include the two wheels at the left for pitch bend and modulation which became an industry standard since, and indeed synth solos with pitch bend became a landmark novelty of the early 1970's rock. They had some reputation for getting out of tune though (a problem referred to as ‘pitch drift’, occurring especially with temperature changes and typical of many early analog synthesizers).

In 2002 a modern version was released, the Minimoog Voyager, still analog and monophonic but with many improvements and MIDI interface. An XL version with extended keyboard was also produced.

ARP (standing for the initials of founder Alan Robert Pearlman) was the main competitor to Moog in the 1970’s. Their first product was the ARP 2500, a big modular synth released in 1970 which anecdotically appeared in the movie Close Encounters Of The Third Kind playing the famous 5 notes phrase to communicate with the aliens. It was also the machine used by The Who’s Pete Townshend for the famous intros to Won’t Get Fooled Again and Baba O'Riley. Unlike the Moog Modular the different modules did not need to be connected by patch cables, instead patching was done by its characteristic Matrix sliding switches which although less intuitive and probably not simpler gave it a much cleaner look.

ARP’s smaller synths were direct rivals of the Minimoog, mostly the monophonic Soloist  / Pro-Soloist (a favourite of Tony Banks) and the duophonic Odyssey.

Another very popular product was the ARP-Solina String Ensemble, a compact polyphonic electronic keyboard belonging more to the family of 'string machines' rather than actual synthesizers (see the Polyphonic Synthesizers entry) focused on a few strings and wind sounds and addressed to rival the Mellotron without its mechanical problems. In 1975 a rare synth version called ARP String Synthesizer was released.


ARP-Solina String Ensemble

String Machines were arguably the first Preset Synthesizers although they are usually not formally considered as ‘synthesizers’ (see the Polyphonic Synthesizers entry). They were invented in parallel and independently by three different people. From one side there was the British Ken Freeman, a private amateur musician with some knowledge of electronics, not working for any instruments company. Based on some insight gained from the Selmer Clavioline from the late 1940’s, he built his first prototype in 1969 and spent the following years refining it and showing it at fairs looking for investors, but it took him until 1974 to reach an agreement with CMI-Lowrey to produce his machine, which was called the Freeman String Symphonizer. 

Parallely, the Dutch organ manufacturer Eminent-Solina came also with their version of a string machine (with different technology, using only one master oscillator as sound source while Freeman’s instrument used a bank of multiple oscillators) and integrated it in their 1972 console organ Eminent 310 Unique, becoming the first string machine commercially available. However the 310 organ was not a ‘rock musician’s pro’ instrument and went largely unnoticed (except by Jean Michel Jarre who used it extensively in his 'Oxygene' album), until in 1974 they detached the string ensemble module from the organ and released it as a stand-alone compact string machine, the Solina String Ensemble. The Americans ARP were also at the time experimenting with a string synthesizer but they were facing quite some problems, and upon seeing Eminent’s instrument they made a deal to sell it rebadged as ARP-Solina String Ensemble, and this instrument was a big success.

Finally, the Italian Logan Electronics released their own version of a string synthesizer in 1973, the Logan String Melody, which would be also commercialized outside Italy with Hohner badge.

The Elka Rhapsody and the Roland RS202 were also popular early string machines.

ARP produced very good analog electronics, their oscillators were more stable against pitch drift than Moog’s, but ARP tended to reuse existing components in their new products instead of really advancing the technology, the company management was not strong and they had a stubborn culture of having to do things differently from their archrival Moog which led them to reject some good ideas appreciated by the musicians, most notably the pitch-bend wheel, ARP’s alternative being either a pitch knob or the weird PPC (Proportional Pitch Control) buttons which never enjoyed much success.


ARP’s PPC pressure sensitive buttons in an ARP Axxe. The left button for pitch-down, the right one for pitch-up and the middle button to produce vibrato.

The 1978 Quadra was another ARP synth widely used by Tony Banks in the period from And Then There Were Three to “Shapes” (Mama).

In the mid 1970’s ARP invested many resources in developing a guitar-controlled synthesizer, the Avatar, but it was a commercial failure and sadly ARP finally went bankrupt in 1981. CBS-Fender acquired the remainings of the company including the design of the last ARP product, the Chroma synthesizer which was in prototype stage and was subsequently launched as the Rhodes Chroma.


Notable ARP users include Tony Banks, Jean Michel Jarre, Kansas, Pete Townshend or Stevie Wonder



EMS (Electronic Music Studios) from the UK did not get quite as big as the Americans Moog and ARP but they released some remarkable products. While most people were focusing on big modular synths costing several thousands of dollars or pounds, EMS launched in 1969 (1 year before Moog released the Minimoog) an extremely affordable little synth, the VCS3, which retailed at just UK£ 330, by comparison the Minimoog would retail at US$ 1,500 which was something like around UK£ 600. Admittedly the VCS3 did not include the external keyboard which needed to be purchased separately if one wanted to use the instrument melodically (the DK1 or DK2 keyboards costing around another UK£ 150) although you could also plug in the signal from some other organ or keyboard, and even without a keyboard it could be used to generate sound effects using its knobs and innovative joystick.

Many of Pink Floyd’s sound effects were produced with a VCS3.

But besides the price tag, the other remarkable characteristic of the VCS3 was that unlike the Minimoog, ARP Pro-Soloist or other small synths which were pre-wired, the VCS3 was a real modular synth with full patching possibilities, just reduced to the basics and a very small size. It had a 16x16 matrix grid where patching was done by inserting colour-coded conductive pins, quite neat. These two features meant that the VCS3 made the world of modular synthesizers accessible to the large public (a specific educational version the Synthi E was eventually produced).

In 1971 EMS released the Synthi A and in 1972 the Synthi AKS, which were both based on the VCS3 but even more portable, contained in a plastic briefcase, with the AKS including a touch-plate keyboard (K) and a sequencer (S).

Shifting from one extreme to the other, in 1971 EMS released also a huge modular synth, the Synthi 100, oriented to studios (the BBC used one frequently for sci-fi and horror sound effects such as for Doctor Who), costing around UK£ 10,000 (depending on the precise specs) and featuring two huge 60x60 matrix patching grids, two duophonic keyboards, sequencer and optionally a vocoder.

In 1972 EMS released what they advertised as a Guitar Synthesizer, the Synthi Hi-Fli, although it was actually a multi-effects processor, albeit a rather sophisticated one for its time, including octave shifting, ring modulator, fuzz and several modulation effects options. It had a waist-height control panel and two pedals which could be assigned to control different parameters.

Pink Floyd's David Gilmour bought one of the prototypes and supposedly he used it in Dark Side Of The Moon and possibly on later albums as well. Steve Hackett also got one.

The archetypal electric piano, the Rhodes was developed by Harold Rhodes in the 1950’s. It generates sound by a sort of tuning forks which vibrations are picked up by electromagnetic pickups. It has a characteristic bright bell-like ethereal sound and was widely used in Jazz-Rock / Fusion and Prog. There have been several versions.

A variation was the Rhodes Piano Bass, a short version with the pitch range of an electric bass, most famously played by The Doors' Ray Manzarek.

The Wurlitzer electric piano (trademarked 'electronic piano' and informally known as 'Wurly') and the RMI Electra-Piano were the biggest rivals to the Rhodes. The Wurlitzer electric pianos were originally released in 1954 but the really successful model for the Prog generation was the model 200 released in 1968. The sound was generated by steel reeds whose vibrations were picked up by an electromagnetic pickup and it was not too different from the Rhodes. The most recognizable and popular use of the Wurly in Prog is the typical Supertramp e-piano sound (they frequently passed it through a chorus or flanger effect). Pink Floyd's Rick Wright used both Rhodes and Wurly, and the electric piano in Queen's 'You're My Best Friend' was also a Wurly.

The RMI (Rocky Mount Instruments) Electra-Piano was the other most popular electric piano next to the Rhodes and the Wurly. But unlike them or other electric pianos which produced the sound by mechanical / acoustic means and then collected them via electromagnetic pickups, the RMI produced its sound completely electronically from transistors, giving it a rather unique sound quite different from a real electric piano or harpsichord. This allowed also a wider palette of sounds, it had piano, harpsichord and lute stops, but also an Accenter which produced a more percussive attack and an Organ Mode which extended the sustain. Rick Wakeman, Jon Lord and Tony Banks were frequent users and the RMI Electra-Piano was the instrument used by Banks for those sweeping arpeggios in the background of 'The Carpet Crawlers'. It's biggest weak point was the lack of a velocity-sensitive keyboard.


RMI Electra-Piano 300 

In 1974 RMI released two revolutionary instruments: The Keyboard Computer was the first portable digital sampler (precisely Rompler), it included 29 fixed sounds but also a punch-card reader where additional cards with other sounds could be inserted. In a sense it was also a bit like a synth in that musicians understanding the principles of the coding of the punch-cards could just experiment by creating their own punch-cards and seeing what sound was coming out from the machine. To top it off, it was 12-note polyphonic. Rick Wakeman became an early fan. Two models were produced the KC-I and the 1975 KC-II.

It is hard to overemphasize how innovative this instrument was for its time, just consider that the painfully long development of the mechanical tapes-based sampler Birotron was just starting by the time the digital KC-I sampler was already on the shops shelves! No other digital sampler would be commercialized until the Fairlight in 1980 (although that was a real sampler not just a rompler like the RMI KC's).

The other revolutionary instrument was the 1974 RMI Harmonic Synthesizer, the first commercial digital synth which was way too ahead of its time and remained rather obscure. It used additive synthesis (opposite to the substractive method usually used in analog synths) and although the technology was monophonic it employed a trick for pseudo-polyphonic results: it had 2 monophonic harmonic sound generators each routed to one of the stereo audio channels. The generator used for accompanying chords had an arpeggiator, so you could play a chord and the instrument would play its notes repeatedly in arpeggio generating a chord effect even if playing just one note at a time, and on the other channel you could play the melody or solo on top (in genuinely monophonic way).

The Hohner Clavinet was a bit like an electrified harpsichord, producing bright staccato sounds. In some sense it was like an electric guitar triggered by keys. Many Prog Rock keyboardists used them, one notable user being Kerry Minnear from Gentle Giant.

Another Hohner keyboard featured in some early Prog was the Pianet, an electric piano more humble than the Rhodes or Wurly and which had some popularity in the 1960's and early 1970's.

Farfisa from Italy produced organs of nice warm sounds, more atmospheric and quite different from the sound of tonewheel organs like the Hammond. The Professional Duo was a very appreciated model. Notable users include Pink Floyd’s Rick Wright, Van Der Graaf Generator’s Hugh Banton or Led Zeppelin’s John Paul Jones.

Farfisa organs were frequently recognised by their big rocker-switches arranged in colour-coded groups, although they were by no means the only ones to use them (this being a reason why The Doors Ray Manzarek’s Gibson G101 organ pictured in the entry for the Rhodes was frequently mistaken to be a Farfisa).

Farfisa also produced some synths such as the analog 1975 Synthorchestra (polyphonic on 4 preset sounds and monophonic for the rest) or the 1979 digital Soundmaker.

The Orchestron was not a prominent instrument in Prog Rock but it deserves mentioning by the fact that Patrick Moraz commissioned a one-off instrument which he used in the late legs of the Yes ‘Relayer’ tour and in his solo album ‘I’. It evolved from an early 1970’s Mattel toy-home keyboard called the Optigan which was actually a sampler (rompler), not too different in concept from the Mellotron except that it had the sounds stored in optical discs instead of magnetic tapes. The home keyboard was not successful and the idea was sold to a company called Vako who presumably saw in it a big potential in the professional music sector as an alternative to the successful but unreliable Mellotron.

The commercial Orchestron was a rather small unit with just one 36-keys manual, but Patrick Moraz liked the concept and commissioned a one-off instrument with 3 keyboard manuals, a bit similar in looks to the Yamaha GX-1, which he used in the later dates of the Yes’ ‘Relayer’ tour and in his solo album ‘The Story Of I’. This 3-manual and also 2-manual versions were planned for mass production but never reached the actual market. Moraz’s unique instrument didn’t last for long as it was damaged beyond repair during some maintenance work.

At any rate, Vako was probably not an experienced enough company in the music instruments business, the quality of the sound samples in the commercial unit was not so good, and the price was high, and the Orchestron was a commercial failure. Only around 50 units of the commercial single-keyboard model were produced and besides Moraz only a few relevant musicians used it, among them Kraftwerk or Rainbow's Don Airey.

All the early 1970’s synths were monophonic (they could only play one note at a time, not chords). In most monophonic synths, if more than one note was played only the last one sounded. Some exceptions like the ARP Odyssey, the EMS Synthi 100 or E-mu Modular achieved duophonic polyphony by actually combining two synths one for each note played, and some complex setups could achieve higher polyphony (for example with the E-mu one could in principle combine up to 10 synths to obtain 10-voice polyphony) but early polyphony methods were not practical and musicians wanted to be able to play chords with their synths.


E-mu Modular 1973

Although not used in classic Prog strictly speaking, when talking about early polyphonic synths it is probably worth mentioning TONTO (standing for The Original New Timbral Orchestra, I don’t know if any pun was intended or not but ‘tonto’ in Spanish means ‘dumb’), the mega-synthesizer assembled and handled by engineers / producers / electronic musicians Malcolm Cecil and Robert Margouleff and used most famously in the four Stevie Wonder albums from 1971 to 1974 (from Music Of My Mind to Fulfillingness’ First Finale) producing many of the sounds featured in hits such as Superstition or Living For The City. Its main configuration was gradually assembled between 1968 and 1972 and it consisted of 3 controller stations surrounded by a hemicycle of modules panels including components from Moog, ARP, Serge, Oberheim, EMS, Roland, Yamaha, and purpose-built ones. It is still considered the biggest analog musical synthesizer ever assembled (it still exists). TONTO was not only polyphonic but also multitimbral, meaning that not only multiple notes but also multiple patch sounds could be played simultaneously from its controller keyboard stations. Cecil and Margouleff released also 2 albums of electronic music with it under the name Tonto’s Expanding Head Band, in 1971 and 1974.

In proper Prog, the first appearance of a polysynth in a studio album was in ELP’s Brain Salad Surgery, with Emerson playing the prototype of the Polymoog, still called Apollo by then and credited in the album as the "Moog Polyphonic Synth Ensemble" since it included also the monophonic solo synth Lyra. Patrick Moraz was another one whom Bob Moog gave the privilege of having a Polymoog prototype. 

At any rate the first commercial polyphonic analog synths were Moog’s Polymoog and the huge 3-manual Yamaha GX-1 (evolved from the Yamaha Electone EX-42 organ and the Yamaha CSY-1 combo of organ plus monophonic synth), both released in 1975. The GX-1 was adopted by Keith Emerson producing a significant change of sound for the band (and divided reactions to it) and seen by many of us in the Works Live tour video, and John Paul Jones and Stevie Wonder were other notable users.

The ARP Omni (1975) was polyphonic but only on two preset sounds Violin and Viola (similar case with the Farfisa Synthorchestra). Other competitors soon followed, the Oberheim 4-Voice (1975), the Korg PE-1000 / 2000 (1976), Yamaha CS-80 (1976), Korg PS-3100 (1977) and notably the hugely successful Prophet-5 by Sequential Circuits (1978, for which Rick Wakeman actively participated in the design of the user interface).

Here it is convenient to point out that in the mid 1970's a particular family of instruments was developed which blurred the until-then generally accepted concept of the difference between an Electronic Organ or Keyboard and a Synthesizer: the Preset Synthesizers, and particularly the sub-set which became known as 'String Machines'. Up to that point the general wisdom said that an instrument providing only preset sounds without any possibilities for editing them and with fixed pitch generation was 'an electronic organ or keyboard', while synthesizers allowed the musician to build the sound from scratch and control every parameter, from the basic sound wave shape (traditionally organs could only produce square waves while synths could also produce sine, sawtooth and triangle) to the envelope and filters, and their tone generators could produce any pitch not just the fixed tone pitches of the chromatic scale keys of the keyboard.

Preset Synthesizers were a sort of hybrid, they generated and shaped the sounds as a synth but the patching and settings determining a sound were pre-programmed, and some of them allowed editing of some parameters, some more than others. Moreover traditional Organ-like instruments started to have variable pitch tools such as portamento and pitch-bend and increasingly advanced features, further blurring the previous concepts. The ARP Soloist / Pro-Soloist were actually preset synths with a few possibilities for editing the sound. Focusing on preset sounds and sacrificing editing possibilities made it easier for the manufacturer to make them polyphonic. Many of these instruments focused on strings sounds and therefore became known as 'String Machines', or as 'Poly Ensembles' when they included other sounds such as brass, winds, pianos, percussions etc. The ARP Omni mentioned above was such an instrument, as well as the Korgs PE-1000 and PE-2000 (PE standing for Poly Ensemble, the PE-1000 dedicated to percussive sounds and the PE-2000 to strings and sustained sounds, while the true variable Korg synths were the PS family).


The Roland RS202 was one of the String Machines in the mid 1970’s, here in Camel's Pete Bardens rig in 1977, on top of a Honher Clavinet D6 and a Fender Rhodes. At his right a Minimoog which was placed on a (not visible) Hammond.

To distinguish them from Preset Synths, 'true' synths with advanced synthesis and editing capabilities were called 'Variable' or 'Programmable' Synthesizers, although there is no precise dividing line between them.

Until the arrival of digital synths polyphony for variable synths was still limited, for example the iconic Prophet-5 had just 5-voice polyphony, in comparison modern upper-level digital synths have 128-voice polyphony (note that polyphony does not only allow playing ‘with more than one finger’, if that was the case 10-voice polyphony would be the maximum needed for any player with two hands. Extended polyphony allows different sounds to be played simultaneously from a set of notes, for example playing 6 fingers with 3 different simultaneous patches will use 18 voices, or it allows maintaining sustain of sounds even after you have already started playing something else etc).

Understanding that there was no definite dividing line between Preset Synths and Variable Synths, one might say that the only fully polyphonic analog variable synths ever made (besides the Hammond Novachord) were the Polymoog (with 71-voice polyphony for 71 keys) and the Korg PS-3100 / 3200 / 3300 (with 48-voice polyphony for their 48 keys). Incidentally, the Yamaha GX-1 had 8-voice polyphony in its 2 lower manuals and the upper solo manual was monophonic. The Yamaha CS-80 was also 8-voice polyphonic.

Rush's Geddy Lee used to play a custom console keyboard which combined an Oberheim 8-voice synth and a Minimoog. This monster was built for him by his technician Tony Geranios in late 1978, who also built an interface by which Geddy could trigger the Oberheim sounds from his Moog Taurus pedals. As from 1982 Geddy's favourite synth became the PPG Wave 2.2 which he combined with an Oberheim OB-Xa and a Roland Jupiter-8.

Another limitation of the 1970’s analog synths was the lack of memory, which was still a very expensive resource. As mentioned before, some models in the mid 1970’s offered some factory presets which the user could take as a starting point and then modify, but the modified patch could not be stored again, the musician had to reprogram the sound every time and for every song. When the musician or engineer found a sound patch he liked he had to write all the settings down in a so-called patch-sheet so he could recover the very same sound at a later moment. Even a monster like the Yamaha GX-1 or the 1977 Korg PS-3100 did not have any memory, and by as late as 1978 even a top-level synth such as the Korg PS-3200 had only 16 user-storable patches. One of the reasons for the Prophet-5 huge success was that it had 40 patches memory (even more in later versions). Synths produced as from the mid 1980’s (both analog or digital) started to have some decent storage memory, for example the successful 1984 Roland Juno 106 had 128 memory patches.

Besides the obscure RMI Harmonic Synthesizer (which actually combined digital and analog technology), the Synclavier by NED (New England Digital) was the first commercial fully digital music synth, and one of the first digital samplers. It was essentially a computer rather than a musical instrument in the traditional sense, the first version released in 1977 did not even have a musical keyboard controller but only a computer-like alphanumeric keyboard. Off-the-shelf personal computer components did not exist yet so the company had to produce all the hardware and software in-house. It allowed both digital sound synthesis and (as from 1982) also digital sampling. It pioneered the FM synthesis method later popularized by the Yamaha DX-7.

A musical keyboard interface was eventually offered in 1979, but the sounds could be triggered from other devices, Pat Metheny used the Synclavier extensively controlling it from his Roland controller guitar.

They were expensive machines and as such many were owned by music studios and producers rather than individual musicians, although some notable owners included Pat Metheny, Tony Banks or Frank Zappa.

The Australian Fairlight CMI (Computer Musical Instrument) was very much a product of the 1980’s and therefore not prominent in classic Prog Rock but it is relevant from an historical perspective as the device, together with the Synclavier, which made the bridge from analog synthesizers and analog samplers like the Mellotron to digital synthesizers and samplers.

Launched in 1979 (same timing as the second generation Synclavier) it was also essentially a computer designed to generate or sample sounds digitally. A characteristic feature was the CRT monochrome screen displaying the sound waveform and patterns, and as from 1982 the 'R page', a primitive graphical multi-track sequencer precursor to modern DAW (Digital Audio Workstations) user interfaces, and including a light pen for selecting and editing the items on display (the Synclavier had also a CRT monitor but with simpler display features).

It is fair to say that the Fairlight was a major revolution in the music scene (the Musicians Union tried to get it banned because of fear that it would put many musicians out of job!), and many artists used the Fairlight in the 1980’s including Peter Gabriel, Stevie Wonder, Geoff Downes, Klaus Schulze, Kate Bush or Queen, but the fast development of digital sound technology caused the expensive Synclavier and Fairlight to gradually decline in favour of more affordable and compact digital synth keyboards such as the Yamaha DX series (1983’s DX-7 was hugely popular and the top-line DX-1, altough expensive was highly regarded), the Roland D-50 or the Korg M1. The Synclavier and Fairlight remained used mainly in studios and also for their sampling capability until more advanced samplers were developed in the mid-late 1980’s.


Another manufacturer deserving mention in that transition period is the German PPG, which achieved significant success in the early 1980’s with their Wave series which introduced the wavetable synthesis method. They were used by many German-school musicians and bands but also many others such as David Bowie, Jean Michel Jarre, Geddy Lee or Geoff Downes as well as many New-Wave bands.

Geoff Downes was one of the first to tour with a Fairlight in the 1982-1983 tour for Asia's debut album. His rig then was impressive, mounted on a scaffolding above the other 3 band members. At a 1983 gig in Japan for an MTV event his rig won an entry to the Guinness Book of Records for being the largest ever played live by a rock keyboardist, with 28 different keyboards (although I suspect, not with absolute certainty, that instruments with 2 manuals were counted as 2 keyboards).

Next row to the right, Mellotron M400 topped by Polymoog, the Fairlight keyboards, 2 Minimoogs and the Fairlight monitor. Next row to the right, Fender Rhodes topped by Hohner Clavinet C6, Solina String Ensemble (with the Fairlight alphanumeric keyboard at its left), and SC Prophet-10. Still further to the right a Hammond B-3 topped by what I think is another Minimoog (but not sure). I know he had somewhere also a Moog Liberation keytar and almost invisible below the CP70 there was also a Moog Taurus. Anecdotically, the arrow shows the hand of some technician adjusting the settings on the Prophet-10.



If the release of affordable digital synth keyboards led by the Yamaha DX-7 provided half of the nails for the Fairlight and Synclavier coffins, the other half came from the first affordable samplers, of which the E-mu Emulator series were perhaps the most relevant. The first version was released in 1982 and it was very basic, but the Emulator-II released in 1984 was significantly improved and even with a price tag of around US$ 9,000 it was quite successful (the Fairlight and Synclavier II costed around US$ 25,000). It used 5 ¼ floppy diskettes as memory media. It was used among others by Genesis Tony Banks, Yes Tony Kaye, Klaus Schulze, Tangerine Dream and a lot of the 1980’s main New Wave bands.

MIDI is not an instrument but it’s a technology which radically changed the way music is created and played, and having reached in our journey the point of the development of the first digital synth keyboards it seems appropriate to dedicate some comment to it.

At the end of the 1970’s some manufacturers started to develop ways to connect different devices from their product line-up, so for example playing from one keyboard you could use also a sound patch from another one, but it became quickly evident that if each manufacturer started developing his own non-compatible technology this would give little benefit for the musicians, who commonly used instruments from different manufacturers.

Dave Smith from Sequential Circuits was the main developer of a proposal for a universal interface between electronic music devices, which he introduced at the Audio Engineering Society show in 1981. The proposal was discussed and fine-tuned between several manufacturers and completed in 1983 with the name MIDI (Musical Instrument Digital Interface).

MIDI messages tell the receiving device information about when and how to trigger a sound (for example bank and program number to trigger, pitch, velocity or vibrato parameters, duration, panning setting etc) but nothing about the sound itself, which is up to the receiving device to generate. However MIDI has enabled much more than simply playing one instrument's sound from another one, it has effectively converted music from an audio product into a 'computer commodity', triggering a whole new world of possibilities including the use of sequencers, exchange of modifiable music files, remote programming and many others.

MIDI has revolutionized the way many musicians create and play music and it fueled the development of numerous new devices such as sequencers and workstations, samplers, drum machines, multitude of non-keyboard controller instruments such as the Synthaxe, the Yamaha G10 MIDI Guitar, the Haken Continuum or the more recent Eigenharp, or even the possibility to control the show lights from the controller instrument.

Many of the important pre-MIDI analog synths can be retrofitted with MIDI interface ports.


Scheme of MIDI connected devices: When switched on the same channel, playing the keyboard will produce its piano sound and also the strings and brass sounds from the sound modules.



It may seem unnecessary and trivial to include such an ubiquotous instrument as the piano in this list, but it would be unfair not to mention it either. The acoustic piano has played a big role in Prog Rock so at least a brief mention is deserved. Many Prog masterpieces owe their magnificence to the delicate yet powerful sound of the acoustic piano, Keith Emerson and Rick Wakeman being prime examples. Obviously there are many brands and each keyboardist had his own preferences but pianos by Steinway & Sons seem to have enjoyed much support from the 1970’s Prog keyboard gurus.

Grand pianos undoubtedly deliver the richest and most refined sound but Keith Emerson gave also some relevance to the humble upright piano with his honky-tonk / ragtime tunes such as Jeremy Bender, The Sheriff or Benny The Bouncer.

If one particular piano deserves mentioning it's Keith Emerson's 1973's spinning piano. He used it very few times due to the complexity of installing its mechanism and because once the keyboard lid closed on his fingers while spinning LOL

In the mid 1970’s some manufacturers, most notably Yamaha, started to produce electric pianos targeted at reproducing the sound of acoustic pianos as closely as possible, rather than producing the typical electric piano sound of the Fender Rhodes, Wurly etc. The Yamaha CP series was very successful in replacing acoustic pianos in live performances thanks to their convenience and convincing sound, with the CP30 being a very successful compact model (used by Keith Emerson and Rick Wakeman among many others) and the CP70 (“Electric Grand Piano”) being a hybrid using actual strings but shorter and with an electric pickup system providing a very convincing reproduction of the sound of a grand piano in a more compact and convenient instrument. The CP70 was part of Tony Banks rig for several years.

Some of the keyboard gurus wanting the top in bombastic and majestic sounds thought that the sound of electric organs was not enough and they wanted to incorporate the sound of the real classical thing, church pipe organs. The first Prog musician to record with a real pipe organ was probably Keith Emerson, playing the Royal Festival Hall organ for 'The Three Fates' (ELP debut album) and later the Flentrop Organ at St. Mark’s Church for ‘The Only Way’ (Tarkus album).

Rick Wakeman followed playing the Mander Pipe Organ at the Church of St. Gilles, Cripplegate, for ‘Close To The Edge’ and later also for ‘Jane Seymour’ (from The Six Wives Of Henry VIII album). This is actually an 18th century organ originally made by Jordan and Bridge in 1733 but completely reworked and maintained by Mander in the 20thcentury.

Rick Wakeman also recorded pipe organ parts for ‘Parallels’ (Yes Going For The One album) and ‘Judas Iscariot’ (from his solo album Criminal Record) using the organ at St. Martin's church in Vevey, Switzerland. Curiously, Rick played the organ in Switzerland and the sound was transmitted in real time to the studio in the UK via a leased telephone line and recorded there in the UK.

Wakeman even used a portable Mander pipe organ in the Going For The One tour.

The Continuum was made popular by Dream Theater’s Jordan Rudess.

Developed by Lippold Haken and marketed as from 2002 the Continuum is a MIDI controller which enables playing continuously changing sounds by sliding one’s fingers through its surface, in some sense it can be considered a descendant of the Trautonium from the 1930’s and the ribbon controller of the Moogs. The interface is a key-less and fret-less neoprene surface with sensors which provide 3-D sensitivity, the position on the X horizontal axis determines pitch and the position on the vertical Y axis and the pressure applied (Z axis) can be programmed to determine for example timbre and amplitude variation. The pitch variation can be programmed to be either really continuum or following the tempered chromatic scale to limit portamento effect. It is 16-voice polyphonic.

The Harpejji is another recent instrument embraced by Dream Theater’s Jordan Ruddess, consisting of a stringed flat platform on which the musician can tap with both hands.

The Theremin is unique enough to deserve some mentioning. Originally invented in 1928 by the Russian Leon Theremin, it produces sounds without actually touching the instrument. Typically it has two antennas and the performer moves his hands around them, the instrument senses the distance and movement of the hands from the antennas and converts them into sound, one antenna determines pitch and the other determines amplitude (volume).

Robert Moog produced Theremins before his breakthrough work in developing the synthesizer. The Theremin produces eerie sounds and has been used by Jimmy Page, Jean Michel Jarre, Keith Emerson, the Spanish Los Canarios in their album Ciclos and other experimental and electronic music.

Some modern Roland keyboards have a so-called D-Beam Controller which uses the movement of the hand in front of a beam of infrared light to control certain parameters or effects, looking similar to controlling a Theremin, you may see it in modern-era Geoff Downes playing.

Keytar is a generic term referring to any keyboard which is operated hung with a strap from the musician’s shoulders in a similar way as a guitar is. In terms of shape, the origins of the keytars can be linked to instruments like the Swiss Weltmeister Basset or the Swedish Joh Mustad Tubon from the 1960’s, but functionally these instruments were oriented to playing accompanying lines in popular music rather than taking the role of an electronic keyboard in rock music.

In the early 1970’s some musicians attempted to play regular keyboards strapping them and hanging them from the shoulders, most notably Billy Preston and Edgar Winter who strapped the keyboard section of his ARP 2600 synth. This led to some keyboards specifically designed to be strapped, such as the Univox/Crumar Compac-Piano or the Hillwood Rockeyboard RB-1, but these were literally strappable keyboards to be played placing the two hands on the keyboard from the top, rather than actual keytars which concept was adopting a guitar-style neck where the left hand was placed from below like in a guitar and was dedicated basically to operate the expression controls such as pitch-bend and modulation or to change the program or parameters, and not for playing on the keyboard which was basically done only with the right hand.

The first commercial mass-produced keytar was the 1980 Moog Liberation although the 1979 Performance Music Systems Syntar should be considered as well, even if its commercial attempts were a failure. The Davis Clavitar was also released in 1980, being just a controller keyboard for monophonic synths while the Moog Liberation and the Syntar were self-contained synths.

However there are two earlier instruments which can be considered as the first genuine rock keytars. The first is the 1977 Probe designed by Utopia’s Roger Powell (Powell had been an engineer at ARP) and built by Royalex. Jan Hammer also helped developing it and he got a slightly different version, Powell’s had a hole for the left hand while Hammer’s had a mini-neck with more traditional thumb-operated expression controls. MIDI did not exist yet and the Probe was a controller keyboard linked by cable to an Oberheim synthesizer.

The other early keytar is rarely mentioned in information sources but it is particularly relevant for the Prog scene since it was played by Rick Wakeman, and importantly it was formally called “The Keytar”. It was built in 1978 by KMI (Keynote Musical Instruments) from the UK and KMI even registered the name “Keytar” so this term could not be officially used by other manufacturers until the registration expired in the 1990’s. Rick Wakeman played the prototype in the 1979 Yes tour (mostly in the solo duel with Steve Howe during Starship Trooper) and also in his solo work, it can be seen for example in the video of Wakeman’s 1979 solo performance of Animal Showdown captured from the German TV show Rock Pop. KMI could not compete with the big companies like Moog or Korg and their instrument never reached commercial production, but it is unfair that they are usually omitted from most historical accounts of the keytar.

So, perhaps ironically, while many Prog purists despise keytars, their early origins were led by progressive musicians like Utopia's Roger Powell, Jan Hammer and Rick Wakeman.

In 1982 Sequential Circuits released the Remote Prophet, a keytar which (as the name obviously suggests) remotely controlled the Prophet-5 via a propietary cable (no MIDI yet).

Keytars became popular in the 1980’s with main manufacturers including Moog, Roland, Korg and Yamaha. Some models were synths on their own but with the development of MIDI many later keytars tended to be just controller keyboards, allowing them to be lighter and cheaper. Although they were mainly used for Synth Pop some Prog and Jazz-Rock / Fusion musicians embraced them such as Rick Wakeman, Geoff Downes or Herbie Hancock.

Muse’s Matt Bellamy has a curious instrument built by Hugh Manson called the ‘Keytarcaster’ featuring a 4-string neck for playing bass notes by tapping with the left hand and a keyboard for the right hand, which he uses for performing Undisclosed Desires.

The Synthaxe became known thanks to Allan Holdsworth, its most fervent supporter and virtuoso player. Released in 1984 it was a MIDI controller combining guitar and keyboard features. The left hand controlled a guitar-like neck, with sensors determining the fingers position and the string bend. The right hand could be used on either a separate set of 6 short strings as in a guitar or on a 6-keys keyboard (or on keys triggering the 3 bass strings, the 3 trebble strings or the 6 strings at once). The neck was in an upwards angle for easier left hand operation. A tremolo bar was also included which could be programmed to control different MIDI parameters.

Despite Holdsworth’s excellent work with it in albums such as Atavachron or Secrets, the Synthaxe was very expensive and required a re-training of playing technique which few musicians were willing to undertake (among all other obvious things, the width of the frets was constant all along the neck, unlike in a normal guitar where the frets become narrower the more you move towards the body, this was supposed to make it easier for the performer but it is unclear whether this was the case or it made it even harder for musicians trained in standard guitars), and sadly it was a commercial failure with less than 100 made.

Obviously there have been plenty of electric guitars around, but in terms of electric rock guitars in the 1970’s there were two major camps, the Fender Stratocaster players and the Gibson Les Paul players.

The Fender Stratocaster, aka the ‘Strat’, was first released in 1954 as one of the first solid-body Rock & Roll guitars, it had great looks with its revolutionary double-cutaway design and the neck headstock with all 6 strings tuning machines together on the top side, and quickly became an icon. Many versions have been produced and many if not most guitarists have customised them or got signature versions so generalizing about it is tricky. It had 3 single-coil pickups and a trademark pick-up selection switch, originally of 3 positions which eventually became 5 providing a very nice range of different tonalities. Another important feature was a standard tremolo-bar bridge in many versions.

Some players found the sound a bit too thin and added humbucker pickups for a thicker sound, mainly on the bridge pickup, which became informally known as ‘Fat-Strats’.

Users are countless including Jimmy Hendrix, Pink Floyd’s David Gilmour, Mike Oldfield or Ritchie Blackmore.

The single-cutaway Telecaster (aka ‘the Tele’) was not much used in Prog Rock, its sound was thin and bright, more adapted to country, blues, jazz and standard Rock & Roll, but it’s an historically important guitar anyway and has been used also by Prog guitarists with certain frequency.

Anecdotically Steve Morse in his early Dixie Dregs days played a customized guitar referred to as ‘The Frankenstein’ with Telecaster body and Stratocaster neck (other heavily customized guitars have been called Frankenstein for example Eddie Van Halen’s most famous instrument).

Next to the Fender supporters there was the Gibson supporters camp and Gibson’s most succesful model was the Les Paul, a guitar originally launched in 1952 which became the other solid-body iconic rock guitar together with the Fender Strat. Same as with the Strat it has received continuous upgrades and received countless customisations by its owners so only some generic statements can be made. A characteristic feature was the 3-position pick-up selection switch on top of the strings.

Although the very first Les Paul had single-coil pickups, Les Pauls in the late 1960’s and 1970’s had 2 humbuckers, making it one of the main differences with the Stratocaster. They also had (in the typical configuration) individual volume and tone knobs for each pickup, effectively offering a mixer for the two pickups, while the Strat (again in its typical configuration) had only one master volume knob, and two tone knobs usually assigned to the neck and middle pickups, the bridge pickup not having tone adjustment. Les Pauls typically did not have a tremolo bar bridge although several guitarists such as Steve Hackett eventually had versions with one.

Users are again countless including Jimmy Page, Robert Fripp, Steve Hackett, Andy Latimer or Pete Townshend.

Although 2 humbucker pickups is the archetypal configuration for the Les Paul, there have been versions with 3 pickups, the most famous in the Prog world being Robert Fripp’s 1959 Les Paul Custom ‘Black Beauty’ which he used extensively during the 1970’s. Phil Manzanera, Pete Townshend or Jimmy Page also used 3 pickup Les Pauls and other players such as Focus’ Jan Akkerman added a 3rd pickup themselves.


Robert Fripp and his 3 pickup Les Paul Custom ‘Black Beauty’

The Les Paul Junior was launched as a more affordable version, with simpler construction and just 1 pickup, and it produced a crunchier, less refined sound yet loved by many guitarists, while the Les Paul Special was something in between, also simpler than the Standard LP but still with 2 pickups. Both were also released in double-cutaway body versions. Another model, the Les Paul Recording featuring 2 low impedance pickups and more elaborate electronics was a favourite of Les Paul himself and it was played occasionally by Jimmy Page or Steve Howe.

The hollow or semi-hollow body Gibsons ES-175, ES-335 and other ES series models were favourite guitars of Steve Howe, Alex Lifeson or Pat Metheny.

Not very prominent in Prog but also an important guitar in the 1970’s Rock scene, Gibson’s double-cutaway model was made famous by guitarists like Black Sabbath’s Tony Iommi or AC/DC’s Angus Young, but it was also used by some Prog artists such as Frank Zappa, Kansas Kerry Livgren or The Who's Pete Townshend.

It was meant as an evolution of the Les Paul and from its introduction in 1961 until 1963 it was sold as the ‘Les Paul SG’, but the Les Paul name was removed since Les Paul himself was not fully satisfied with some of its characteristics.

Next to Fender and Gibson, Ibanez from Japan was the next major player in the electric guitar business. They were not too prominent in the 1970’s Rock scene but they were very appreciated in the Jazz-Rock / Fusion scene, and the brand sky-rocketed in the 1980’s with their immensely successful line of metal-oriented guitars.


Pat Metheny with his signature Ibanez PM200



Nylon and 6 or 12-string acoustic guitars were fundamental to classic Prog, from the gorgeous trio playing of Steve Hackett, Mike Rutherford and Tony Banks in the beginning of Supper’s Ready to Greg Lake’s ballads, Steve Howe’s The Clap or Alex Lifeson intro to A Farewell To Kings, nylon and acoustic guitars have provided some of Prog history’s most magical moments.

Obviously countless brands and models were used, Ovation, Martin, Gretsch, Gibson or Zemaitis being popular.

An acoustic guitar familiar to classic Prog fans is the one Greg Lake shows in the ELP Works I album inner sleeve, with a heart-shaped sound hole and pearl-inlayed body. This guitar was custom made for Lake by Zemaitis in 1975 but Lake did not really like its sound and one day he lost his temper and smashed it. His favourite acoustic guitar was always the Gibson J-200. Many years later people still kept asking him about the heart guitar and he finally got Gibson to build him a custom J-200 recreating the look of the Zemaitis, which he played with the Ringo Starr & His All Starr Band in 2001.

Jethro Tull's Ian Anderson used to play a small-bodied Martin 0-16NY (small-bodied acoustic guitars are known as 'parlour guitars'), a guitar which Joan Baez had popularized in the 1960's and which could be fitted with either nylon or light-tension steel strings. Recently he plays an even smaller-bodied parlour built for him by luthier Andy Manson following the design of a traditional French guitar from the 19th century.

Mandolins have also been featured in Prog, and more rarely also banjos or ukuleles.

Guitars are 6 string instruments, aren’t they?

Well it seemed so until the late 1980’s when Frank Zappa’s disciple Steve Vai thought that 6 was not enough, and he got Ibanez to build him a 7-string guitar. Originally he tried having the 7th string to be a higher note (a high A compared to the standard 1st string E) but the string had to be so thin that it broke frequently so he changed to the opposite, having the extra string as a super-low B (compared to the standard 6th string E). The result was very powerful power-chord sounds and extended ultra-low soloing range, very effective for music based on these two techniques rather than full chords, and after Vai’s seminal album Passion And Warfare Ibanez 7-string guitars have been quite successful.

With one more string the traditional chord and scale forms were no longer the rule, eventually people started to experiment with alternate tunings which opened new possibilities, explored mostly in the Metal genre for example by Steve Vai’s disciple Devin Townsend.

Since then many metal guitarists have embraced 7-string and even 8-string guitars, Tosin Abasi from Animals As Leaders or Meshuggah’s Fredrick Thordendal and Marten Hagstrom being notable 8-string guitar players.


Ibanez M8M 8-string guitar (Meshuggah)

Not relevant for classic Prog but now that we mention multi-stringed guitars, a short digression about the curious BC Rich 10-string configuration. Normal guitars are 6-stringed, or 12-stringed where each string is doubled in unison or with one octave shift producing a richer, natural chorus-like sound.

BC Rich guitars were popular in the late 1970's and 1980's among hard-rock and metal guitarists for their unusual aggressive shapes and excellent sound. The model Bich 10 had a 10-string layout where the first 4 strings were doubled and the last 2 were not, providing a hybrid sound with rich trebbles and powerful dryer basses (this is something some players did on 12-string guitars, just not installing the double string on the bass notes). The standard 6 strings had the tuning machines on the neck headstock as usual, while the 4 double strings (which could be installed or not, so it could be also a regular 6-string guitar) were installed in the opposite direction with the tuning machines in the body. 


The string configuration of the BC Rich Bich 10

A curious and failed instrument was the 1995 9Stein invented by Michael Reizenstein, which claimed to be equivalent to a bass and a guitar combined in continuous pitch progression, with all 9 strings tuned in consecutive fourths. However this concept more or less resurrected in the year 2000 with the NS/Stick which combined these principles with the Chapman Stick ones (see the Warr Guitar entry).


The unsuccessful 9Stein



Queen’s Brian May handcrafted his own guitar together with his father in the mid-late 1960’s and for sure they succeded, giving it not only a very unique and recognisable shape but also getting one the most unique tones in the history of rock guitars. They built the guitar with very limited economical resources, using wood from an old fireplace, the tremolo arm being made from a bicycle saddlebag holder or the tremolo itself using springs taken from a motorcycle engine valves. However they were extremely thoughtful in seeking design excellence and their guitar included many features which were much ahead of its time, such as the zero fret, the fact that the pickguard and all the other hardware could be removed in order to service the guitar without removing the strings, and especially the design of the bridge-tremolo set, including string rollers in the bridge, its famous knife-edge tremolo design, or the careful straight alignment of the strings in the headstock to minimise friction ensuring that the strings would get back in tune after tremolo operation.

The Mays also re-coiled the pickups and designed the wiring and there probably lies the secret of its personal sound. Brian’s habit of using a sixpence coin as plectrum probably contributed as well.

Another distinctive feature is the individual on/off switches and phase shifters for each pickup, possibly more difficult to manage quickly but enabling more possible combinations than traditional 3 or 5 position switches.

As far as I know it was also the first electric guitar to feature a full two-octave (24 frets) fretboard.

It's a telling fact that even after Brian becoming a wealthy star able to afford any instrument he wants or making a new and better version of it, it's still his original guitar which he plays the most (although he has a couple of newer replicas), and when it received a thorough maintenance in 1998, the neck didn't need any adjustment at all, it was still perfect from its first day.

Endorsed replicas of the Red Special have been marketed by Guild and Burns, and as of 2004 by his own company Brian May Guitars.

While the costly development and unsuccessful sales of the Avatar guitar-controlled synth was largely responsible for the sad demise of ARP, Roland was the manufacturer which did not give up and eventually achieved success in this field. The ARP Avatar received input from a special hexaphonic pickup which could be installed on any guitar (the term 'hexaphonic' here applied to the pickup only, meaning that it could pickup signals from any of the six strings, the synth itself was monophonic), but Roland thought that it would be better to offer a complete package of synth plus guitar in order to be sure that the instrument would have a consistent performance and a recognizable sound. However Roland was not a guitar maker so they collaborated with Ibanez for building the guitars.

Roland’s first commercial guitar synth was the 1977 GR-500 with GS-500 guitar controller but it was not successful, it required a change in playing style (for example it was important to dampen any strings not being played to avoid unwanted noises) and although it included some clever polyphonic operation in some of its sections like the 'Polyensemble', the true synth section ('Solo Melody') was monophonic.

The turning point came with the release of the truly polyphonic GR-300 in 1980 with the G-303 controller guitar (or the more expensive G-808 which was not so succesful). This synth was a big success thanks to being polyphonic and to the fact that the G-303 was an excellent guitar in itself, and many important players embraced it, Pat Metheny, Robert Fripp, Andy Summers and Adrian Belew among others.


The Roland GR-300 Guitar Synth with the G-303 Guitar

Developing a 6-voice polyphonic synth (one for each string) was not so much of a problem by 1979, but another issue was developing a suitable pickup. Traditional pickups merge the sound of the 6 strings into a single signal but the synth needed to receive each string as an isolated signal one for each voice. Besides 2 traditional humbucker pickups to produce normal guitar sounds, the G-303 / 808 had a special pickup next to the bridge which was in fact 6 tiny pickups, one for each string to feed the synth. A feature of these pickups was that they could feedback vibration back to the strings achieving infinite sustain.


Detail of the synth pickup in the G-303

Robert Fripp and Adrian Belew with their G-303's

Robert Fripp noted that the guitar-synth had some limitations which required approaching it as a new instrument with its own playing technique and not simply utilizing standard guitar playing techniques with it. The limitations he was referring to were mainly some delay from the moment of picking until the sound was produced, which prevented fast picking phrases with good tempo accuracy, and a tendency to pickup sympathetic vibrations from the strings adjacent to the one you were playing.

The G-303 could also be made to control other synths and from 1983 it was offered in package with the Synclavier II.

A next generation came with the GR-700 synth and its very 1980’s shaped G-707 controller in 1984. Nowadays Roland continues producing guitar synths but no guitars anymore, the special pickups can be easily installed on any guitar.

The E-Bow is not an instrument in itself but a battery-powered device which is held with the picking hand and placed in front of the guitar (or other steel-string instrument) strings and emits a magnetic field causing the strings to vibrate, producing a smooth and infinitely sustained sound. Pitch is controled with the fretboard hand as usual. Slowly approaching the E-Bow to the strings creates a slow-attack sound which can be then sustained for long, mimicking the sound of violins, flutes etc.

The Lap Guitar is an evolution of the Steel / Slide playing technique on regular steel-stringed guitars, where a tube of metal or glass (usually put on one’s finger) is slid along the fretboard producing a portamento effect (continuous pitch change opposite to to the quantized chromatic pitch shift of the frets). The tube is called a Steel and the technique uses Slide, thereby the two names are interchangeably used (sometimes it is also called Bottleneck Guitar playing). Steel playing probably started in Hawaii in the 19th century. One can play with a Steel with the guitar hung in normal position, but players realised that placing the guitar horizontally on one’s lap gave them more control on the fretboard hand movement, placing it from above the neck instead of from below. From there it was only a matter of time that specialized horizontal instruments would be developed, the Lap Steel Guitars. They exist since the early 20th century and were commonly used in country and bluegrass, and eventually they got electrified same as regular steel-string guitars.

Steve Howe and Pink Floyd’s David Gilmour are notable players.

A variation of the Lap Steel Guitar is the Pedal Steel Guitar, which additionally has some pedals and rods which the musician can operate with his feet and knees to produce pitch bend, volume control or other effects.

John Paul Jones had a curious 8-string steel bass/guitar manufactured by Hugh Manson, the Lapaphone, which is a hybrid between a traditional strapped instrument and a horizontal Lap one, the strings plane is tilted 45 degrees so the performer can play over the top of the neck as in a real Lap but still enjoying the mobility of a strapped instrument (this design is based on the Melobar from the late 1960’s). The squared screen below the strings is a Kaoss 2-D MIDI controller (also included in some guitars Manson has built for Muse’s Matt Bellamy).

The hippie and psychedelic movement in the 1960’s sparked an interest in Eastern mysticism and culture, and notably The Beatles’ George Harrison became a follower of Indian / Buddhist music and fueled an interest in the sitar. Danelectro saw the opportunity and developed the Coral Electric Sitar, released in 1967, which mimicked the peculiar sound of the Indian instrument but was easy for western guitarists to play with its familiar 6 string neck and standard guitar tuning. The sitar-like sound was achieved thanks to a special ‘buzz-bridge’ and 13 sympathetic ‘drone’ strings (all of 0.10 gauge but different lenght) located on top of the regular 6 strings. Danelectro stopped business in 1969 so these instruments became quite sought after in the 2nd hand market until Jerry Jones Guitars restarted its production in the 1990’s, respecting the Danelectro design but improving a couple of points, mainly the stability of the buzz-effect adjustment and tuning.

A very similar concept was used in the custom Gibson acoustic J-200 built for John McLaughlin in 1975 and which he used with the Indian-oriented band Shakti. It had 7 drone strings which could be either strummed or simply allowed to sympathetically vibrate, producing a buzzy sitar-like sound. He had 2 versions, one with body cutaway and one without.

If on the electric guitar camp the main rivalry was between Fender and Gibson, in the camp of bass guitars Gibson was not so strong (although they produced some fine basses such as the Ripper, the Grabber, the Les Paul or the SG / EB series).

In bass guitars the main rivalry was between Fender and Rickenbacker.

Fender’s most popular bass was the Precision Bass (aka P-bass), following the Stratocaster guitar design. They often featured a single-coil split pickup.

Another very successful model was the Fender Jazz Bass (aka J-bass), recognizable because the volume and tone knobs are mounted on a separate guard (usually chromed).

Fender bassists are also countless, Greg Lake, John Wetton or Roger Waters among them.

The Fender bass sound was smooth, deep and warm. By contrast the Rickenbacker (commonly referred to as 'Ric') was crisper, with powerful trebble notes great for soloing or lead phrases but also a devastatingly fat bass tone. The most famous models are the 4000 series, mainly the 4001 and 4003. Yes’ Chris Squire, Rush Geddy Lee or Genesis Mike Rutherford played Rickenbackers frequently.

Several Rickenbacker 4000 basses: a 4003S/8 (8-string), a 4005, a 4004, a 4003S and a 4001 (S standed for Short Scale, a shorter neck)

Rickebacker produced also guitars and they were very popular in the 1960's (not least because The Beatles or The Byrds used them) but they rather fell out of fashion in the 1970's, although some guitarists still used them such as Steve Howe, Mike Rutherford or Phil Manzanera.

Some players explored fretless instruments which provided a smoother, portamento-oriented sound probably coming from traditional jazz contrabass influences. Fretless technique is quite demanding on the fretboard hand, not only regarding the accurate fingers position for precise pitch but also the way the finger needs to be pressed against the fretboard for good sustain, legatto's etc.

Jaco Pastorius modified one of his Fender Jazz  basses to make it fretless and was one of the first modern bassists to promote it. Fretless bass was mostly used in Jazz-Rock / Fusion but also several more traditional Prog Rock bassists have used it including Geddy Lee or Roger Waters.

Some instruments are 'lined fretless basses' where the frets are replaced by lines on the fretboard, others may have dot markers on the fretboard although this is unusual (frequently this betrays a bass which has been defretted), usually they have markers only on the top side of the neck.

Incidentally, fretless guitars exist as well although they are rare, their sound is damped and technique is very demanding, but some Prog and experimental artists have used them such as Frank Zappa, Adrian Belew, Steve Vai or Andy Summers.

Although basses were traditionally 4-string instruments, following the same trend as electric guitars several musicians and manufacturers started experimenting with more strings, and nowadays 5 and 6 string basses are quite common (even some with more strings, whose practical playability is questionable).

Dream Theater's John Myung playing an Earnie Ball Music Man Bongo 6 6-string bass

Rob Van Der Loo (Sun Caged, Epica) with his custom Conklin 9-string bass

A different variation of multi-string basses are the 8-string basses consisting of 4 doubled strings, following the same principle as 12-string guitars, such as the Alembic played by Greg Lake around 1977 or the Rickenbacker played by Chris Squire.

Greg Lake playing his 8-string Alembic bass

Rickenbacker made two prototypes in the early 1970’s for an 8-string 4000 series bass, one for The Who’s John Entwistle and one for Yes' Chris Squire, both with the rare ‘potato’ headstock shape, and the model was eventually produced as the 4008 (also available were the 4001-4003 / 8 which were an adaptation of the standard 4001-4003 to 8 strings, while the 4008 was designed on purpose to be an 8-string). After the Going For The One tour Squire’s 4008 prototype got damaged and he replaced it by an 8-string Ranney, and gave the damaged Ric to Vincent Gallo (who incidentally is godfather to Chris’ son Cameron).

A curiosity for those who like details: Chris Squire wanted the string pattern opposite to Entwistle, that is, in each pair of strings he wanted the fundamental (thick) string below and the octave (thin) string on top, while Entwistle used the standard layout found in 12-string guitars with the fundamental thick string on top and the octave thin string below. The reversed layout favoured by Squire was better for playing bass without a pick, which is usually done with fingertip strokes from below upwards, rather than guitar strumming which is mostly from top downwards, so the first string to be touched and therefore dominant in the sound is in both cases the fundamental. The ‘potato’ headstock of the prototypes had normal bass tuning machines for the fundamentals and smaller guitar-like tuning machines for the octaves. This meant that the headstock tuners layout had to follow the strings order, so Squire’s bass had the opposite tuners layout (starting from top thin-thick-thin-thick etc) compared to Entwistle’s (thick-thin-thick-thin etc). After some production units still with ‘potato’ headstock (but ‘upside-down’ shape compared to the prototypes) and still asymmetric tuners layout, 8-string Rics were fitted with the standard ‘cresting wave’ headstock shape and 8 tuners of the same size which allowed to easily apply any of the two string layouts. Squire’s layout with the fundamental string below is the most common for doubled-string basses.

There are also 12-string basses, either with the 4 standard strings tripled or with 6 doubled strings, and even 18 string basses.

Evolved from the prototype Taurus from the Constellation Ensemble (see the Moog Modular Synth entry), the Taurus pedals were yet another innovation by Moog. Most organs had always had bass pedals but they got somehow lost with the advent of the electronic keyboards and synthesizers. Moog thought that this needed not be the case and conceived the Taurus, but perhaps it was a bit surprising that after having conceived it as a bass pedals synth module for keyboardists it was actually bassists who enthusiastically embraced it. Most Rock keyboardists played standing up and they frequently moved around different keyboards, and this made it impractical for them to operate pedals. Bassists on the other hand were more free, it was already a standard practice for guitarists to operate multiple effects pedals while the availability of pedals for bassists was more limited, so they had still room to take in some more work, and it was about bass lines anyway.

In any case the Taurus was not really the first instrument of its kind but it was a big step forward compared to previous similar devices. In the late 1960’s a company called Dewtron was producing the Mister Bassman pedals, used by Genesis Mike Rutherford / Tony Banks and Yes Chris Squire / Jon Anderson, but this was more like the detached bass pedalboard from a traditional electric organ, not really a bass synth, and its sound was rather simple and soft. The MusiConics BassMate from the early 1970’s was more advanced but its capabilities were also rather basic compared to what the Taurus would offer.

The Moog Taurus was released in 1975 and many Prog bassists embraced the instrument to complement their sound, as it offered an unbelievably powerful and sustained super-bass tone, unheard of at the time, especially in live playing where it provided a kind of early surround, you felt it more than you heard it.

The Taurus I had 13 pedals, 3 preset sounds and one user programmable sound (without storage memory). In 1981 the Taurus II was launched with 18 pedals and a control panel which could be placed on a stand at waist height for easier programming, but it did not enjoy the success of the Taurus I.

In 2010 Moog released the Taurus 3, again with 13 pedals and attempting to recover the genuine Taurus I sound in an updated machine.

Notable users include Genesis Mike Rutherford, Rush’s Geddy Lee, Yes Chris Squire or Led Zeppelin’s John Paul Jones.

In this entry I am putting together some other guitars and basses played by great Prog musicians or important enough in the classic Prog period to deserve mentioning (multi-neck instruments are mentioned in a separate entry below).

Paul Reed Smith (PRS) guitars are highly appreciated and have been the choice of numerous top-level guitarists including Santana, Opeth Mikael Akerfeldt, Steven Wilson, Al Di Meola and many others.


Steven Wilson with a PRS SingleCut. Other PRS models he plays include the double-cutaways Custom 22/24, Modern Eagle and P22

Another special guitar played by Steven Wilson is the AlumiSonic 1100 made of aluminum alloy. At any rate this was nothing really new, Veleno had been building aluminium-body guitars since the early 1970’s.

The Earnie Ball - Music Man guitars are also excellent, played by guitarist such as John Petrucci, Steve Morse or Steve Lukather.

Music Man basses have also an excellent reputation, played by top-level musicians such as Tony Levin or John Myung.

The Gibson Flying-V and Explorer:


These guitars were not common among Prog guitarists but they achieved quite an iconic status among Metal bands in the 1970’s and 1980’s. Seeing the huge success of the Fender Stratocaster, Gibson felt that they needed also some really modern-looking solid-body guitars, and in 1957 they came up with 3 bold ‘Modernistic’ designs: The Flying-V and Explorer came into production in 1958 but ironically they were too futuristic for their time and remained unsuccessful until the Heavy Metal wave of the 1970’s. The 3rd design was the Moderne which did not see mass-production until a ‘reissue’ version was finally produced in 1982.

A famous bass inspired by the Gibson Explorer shape was John Entwistle’s Alembic ‘Spider’ (sometimes also referred to as Exploiter or Explorer).


John Entwistle playing his Alembic 'Spider' or ‘Exploiter’ 4-string. He had also a version with a V-shape headstock and also an 8-string version.

Another bass which has become familiar to Prog fans is Chris Squire’s Mouradian featuring his initials CS in the body design.

As mentioned earlier, Gibson’s basses were not as successful as their guitars, but some players chose them too.

Entwistle also played a custom bass with Gibson Thunderbird body and Fender Precision neck, nicknamed the ‘Fenderbird’

Another custom bass characteristic of Entwistle in his early years was the ‘Axe’ built by luthier Peter Cook, based on the components of a Fender Jazz bass.

Billy Sheehan is undoubtedly another rock bass maestro, and observant people may have noticed a peculiarity in his signature Yamaha Attitude II bass, the scalloped frets (precisely the frets 17 to 21 are scalloped for the first two strings G and D). The scalloped frets facilitate string bending-up, since besides the bend produced by pushing the finger upwards, applying extra pressure on the string pushes the string into the extra fret depth providing additional note sharpening. This is especially helpful in a bass guitar where the strings are not as easy to bend up as in a guitar, and thanks to this Billy can for example get a high G by bending from the 21st fret on the G string (which would naturally play on the 24th fret).

Scalloped frets also help getting more sustain. A less radical alternative are the so-called jumbo frets, where the fret metal wire profile height is bigger than in standard fret wire. Another feature in Sheehan’s Attitude II bass is the ‘Hipshot D-tuner’ which downtunes the low E string to D with the flick of a small lever in the tuning machine. These 2 features extend the practical range of the bass and they are partly responsible for Sheehan’s notorious loyalty to 4-string basses.


Scalloped frets 17 to 21 in Billy Sheehan’s Yamaha Attitude II bass

A player pioneering the use of scalloped frets in his Fender Strat guitar was Richie Blackmore, and Yngwie Malmsteen also uses them, but scalloped frets in a guitar have a wider purpose than just helping sustain or facilitating bending-up. Scalloped frets are sometimes used for educational and training purposes as they force the player to develop a light touch technique, since if you press the string too hard it will bend up and sharpen the note audibly (too light and it will produce fret buzz). When the correct pressure is applied the finger and the string do not touch the fretboard wood, the string touches only the metal fret wire, and the precise amount of pressure is required to produce the correct pitch, so scalloped frets help the player learning to apply as little pressure as possible, just enough to avoid fret buzz but not any more than that. Frequently only the higher frets are scalloped, which is the area where very fast soloing is more frequently performed. Besides speed with less effort, a player who has mastered the scalloped neck technique can also take advantage of it to produce vibrato and subtle variations of pitch by controlling the pressure applied with the fingers on the strings, without resorting to string bending.

Alembic built high-end instruments, their basses being particularly appreciated and played by people like John Entwistle, Greg Lake, John Paul Jones, Stanley Clarke or (out of the Prog world) Level 42’s Mark King. Alembic was halfway between a craftsman luthier and a small standard builder, although they had some standard catalog models their instruments were basically built by hand and they always put much focus on custom instruments (which among other things meant that they were expensive). It is said that the body tail shapes featured on many of their instruments (the several ‘sting point’ or ‘omega’ variants) were designed to force the musicians to always leave their instrument on a stand, since most of the repairs they faced were damages caused by the instrument being left standing on its body tail and falling down. Another reason why Alembic never became too widespread was their strict ‘no endorsements’ policy, every musician had to pay for his instrument. Regarding guitars, Alembic is most known for having built some for The Grateful Dead’s Jerry Garcia, although Garcia’s most famous guitars such as the ‘Tiger’ were actually built by ex-Alembic employee Doug Irwin following a construction and style very similar to actual Alembics.

Zemaitis was also a craftsman who gained a respected status with his spectacular guitars and basses adorned with elaborate engravings and inlays. He introduced the ‘Metal Front’ and ‘Pearl Front’ concepts alleging some presumed sound quality arguments but mostly attractive for their aesthetic appeal. Zemaitis built some guitars for Greg Lake, including his double-neck, for Jimi Hendrix (his 12-string acoustic) and also for customers such as Ron Wood or more recently Richie Sambora.

Adrian Belew used to play a Fender Mustang significantly modified, with electronics derived from the Roland G303 to control the GR300 synth, and in recent years he plays mostly Parker guitars.

Utopia’s Todd Rundgren Veleno Ankh guitar used in the ‘Ra’ tour possibly inspired Prince’s ‘Love Symbol’ guitar from the 1990’s

Phil Manzanera in the 1970’s played frequently a red Gibson Firebird V11. This kind of headstock with all tuning machines on the same side but upside down compared to the typical Fender Strat layout (on the lower side of the headstock instead of on the upper side) is usually referred to as ‘reverse headstock’.

Charvel / Jackson guitars were mostly adopted by Metal players, since Charvel made its reputation with their guitars inspired in Eddie Van Halen’s Frankenstein (informally known as ‘Superstrats’ since they were meant to be more modern interpretations of the Fender Strat concept) and Charvel’s spin-off Jackson was created after having built the signature instrument for Randy Rhoads with the Jackson name for fear of it being unsuccessful and harming the Charvel name, but they were also played by more progressive musicians such as Jeff Beck, Allan Holdsworth or Shawn Lane.

A similar comment can be made regarding Hamer guitars, they were mostly popular among Metal musicians but several Progressive guitarists have played them such as Jethro Tull’s Martin Barre, Dweezil Zappa or Andy Summers.

A special mention must be made for the Steinberger headless basses and guitars which became quite popular in the 1980’s. The industrial designer Ned Steinberger was requested by luthier Stuart Spector to develop a new bass design, which became the appreciated NS Spector bass of 1975. During this assignment Steinberger started questioning all the basic features of the traditional electric bass design and in 1979 he came up with a revolutionary alternative proposal: by removing the headstock the instrument would be more balanced and feel much lighter, the tuners could be positioned in the body and strings with balls on both ends would make string change much quicker and tuning more stable. The body shape could also be minimalistic to reduce weight, and advanced materials such as graphite, carbon fiber and composite resins would be used. Steinberger introduced the resulting L-Bass design to several manufacturers but they all turned him down so he finally decided to set up his own company to produce them. Despite its high cost the instrument was an immediate success and soon bassists like Tony Levin, Geddy Lee, Mike Rutherford, the Dixie Dregs’ Andy West or Sting were playing Steinbergers.


Geddy Lee playing a Steinberger L-Bass

Guitar versions followed in 1984 and they were also adopted by musicians such as David Gilmour, Allan Holdsworth, Steve Howe, David Bowie or even Eddie Van Halen. Another revolutionary feature was the Transtrem tremolo bridge which besides maintaining all strings in correct relative pitch during even extreme pitch bends with the whammy bar, allowed transposing the tuning through 6 keys with instant locking. Already in the 2000’s Steinberger introduced the also innovative Transcale integrated capo system.

Eventually Steinberger sold his company to Gibson and started another project, NS Design, which besides headless basses focuses mainly on electric instruments which can also be bowed, their line-up including double bass, cello, viola, violin or the 'omni-bass' which can be played either as a normal strapped plucked bass or bowed in vertical position.

Allan Holdsworth has always remained a big supporter of headless guitars and besides genuine Steinbergers he has also played Carvin guitars (also models with headstock such as the HF2) as well as custom made guitars by luthiers Bill DeLap or Ed Roman following the Steinberger principles (Ed Roman used to work for Steinberger).

Another curious instrument is Jon Anderson’s custom MIDI Backpacker, which he built together with a company called L.R. Baggs based on the body of a Martin Backpacker, the neck scroll of a viola attached to the headstock and MIDI electronics with which he can trigger 5 different instrument sounds.

John Mitchell from Arena / It Bites / Frost etc used to play Ibanez but more recently he uses mostly Cort and PRS guitars

Saga’s Ian Crichton is another guitarist with a highly personal sound, all the more impressive since he barely uses any effects at all. Besides an Ernie Ball Music Man, his other main guitar is a Lado.

Another quite special guitar is Uli Jon Roth’s Sky Guitar which he himself designed, featuring an exceptionally long fretboard and a body design without lower horn, allowing reach to exceptionally high notes (it has 6 octaves range in its 7-string version). The highest frets should be so narrow that actually there is a metal fret wire only every two semitones. He has versions with 6 and 7 strings, and a limited run of endorsed replicas has been produced by Dean Guitars.

Resonator Guitars (Dobro)


Resonator guitars, often generically called Dobro guitars which was the main manufacturer together with National, were not common in Prog but they may deserve a short mention. They were developed in the late 1920’s to produce a louder sound than the pre-electric acoustic guitars so that they could be audible among horns and other brass-band or orchestra instruments, this was achieved by integrating metal cones (resonators) in the body. The body itself may also be made of metal but not necessarily. They became mostly used in Blues and Bluegrass (frequently for Steel playing) and more recently they became familiar to the large public due to one (a Beltona Southerner) featuring in the album cover of the Dire Straits’ Brothers In Arms album.

Not relevant for Prog as far as I know, but a curious (and unsuccessful) instrument developed in the 1970’s was the Guitorgan. Guitorgans were electric guitars which included also additional circuitry to trigger the sounds from an electric organ (in some models the organ sound generator being integrated in the guitar body itself, or otherwise sending the signal to an external organ sound module). The metal fret wires were split in 6 sections and each section was a switch closing the circuit to produce on an organ the note being played, so when pressing a string on the neck the pressure on the fret wire would close the circuit and trigger the organ sound. If the string was picked at the same time, the note sounded in both the guitar and organ sound simultaneously. The guitar sound and the organ sound were independent so they could be played individually or both combined.

As part of the frequent Prog maxim of ‘more is better’, many Prog Rock guitarists and bassists embraced double-neck instruments, and although some people may say that it was more for the show than anything else there is no denying that especially for live playing they offered the musicians an increased sound versatility.

Although Led Zeppelin’s Jimmy Page was the first to really popularize the double neck guitar with his candy-red Gibson EDS-1275 (6 and 12 string guitar, which allowed him to play the different sections of Stairway To Heaven live without having to swap guitars), the EDS-1275 had actually existed since 1963, but it was so unsuccessful that it was even discontinued by the time Page commissioned his one to Gibson.

The EDS-1275 is actually older than what some people think… (the version in this picture featuring two 6-string necks of different scale length is strictly speaking an EBS-1250 model)

Steve Howe with a Gibson EMS-1235, mandolin plus 6-string guitar

In the 1970’s double neck instruments became popular, the configuration depended on each musician’s taste, bass and 6-string guitar, 6-string and 12-string guitar, bass and 12-string guitar, which one was on top and which one at the bottom etc.

A common problem was weight, making them tiring to play for a long uninterrupted period of time.

 Notable users include Genesis Mike Rutherford, Rush’s Geddy Lee and Alex Lifeson or Led Zeppelin Jimmy Page.

Mike Rutherford had a curious double neck, a Custom Shergold Modulator which could be assembled as a double neck (bass and 12-string guitar) or disassembled and played as two separate instruments.

Mike Rutherford has also had custom double necks combining two instruments from different manufacturers. For the 1974 Selling England By The Pound tour he commissioned luthier Dick Knight to put together two instruments Mike had, a 1965 4-string Ric 4001 bass and a 1973 12-string Ric 360/12 guitar. This was before Rickenbacker had released the stock 4080 double neck, and it had the guitar neck on top and the bass below, opposite to what the stock Ric 4080 would have. A bit later for The Lamb Lies Down On Broadway tour he had another double neck made combining a Micro-Frets 6-string bass (actually more a baritone guitar) and a Ric 12-string guitar, and for the Trick Of The Tail tour he had another double neck consisting of Micro-Frets baritone 6-string and 12-string guitars. As from then he used mostly the Shergolds, but for the 2007 tour he had another custom double neck combining a 12-string Gibson guitar and a 4-string Yamaha bass.

Another famous double neck guitar is John McLaughlin’s Rex Bogue ‘Double Rainbow’ 12/6. McLaughlin had been playing a standard Gibson EDS-1275 until then (it was 1973, in his Mahavishnu Orchestra period), when luthier Rex Bogue built him this unique piece of art roughly inspired in the Gibson but much more elaborated with those amazing carvings and inlays and clever design for the 12-string headstock so it would look symmetric to the 6-string one. Eventually Ibanez released a stock double neck loosely inspired in the ‘Double Rainbow’, the 2670 Artwood Twin.

Allan Holdsworth maintained his predilection for headless guitars also for double necks. In the picture below we see him with a custom headless double neck made by luthier Ed Roman following the Steinberger principles, with two 6-string necks, a baritone on top and a standard below. Baritone guitars have a longer neck (typically with a scale length of 27 to 28 inches compared to the standard guitar scale length of 24.75 or 25.50 inches) and are tuned lower (typically a 4th lower in all strings).

Given the huge success of Fender’s both guitars and basses it is perhaps surprising that Fender never seemed to care much for double necks, although some have been built under their Custom Shop moniker.


Yngwie J. Malmsteen with his signature Fender double neck STW230-YM 12/6



When Rick Wakeman was preparing his Journey To The Center Of The Earth tour, he wanted something special for the show and he commissioned Wal guitars to manufacture a triple-neck instrument (according to some sources it was the King Arthur tour, I’m not certain which is right). The monster was played by his bassist at the time Roger Newell but it belonged to Rick and when he returned to Yes for the Going For The One album he took it with him and lent it to Chris Squire.

It had a (lined) fretless bass at at the bottom, a fretted bass in the middle and a 6-string guitar at the top. It became Chris’ choice instrument for the live performance of Awaken, and when Rick left Yes again he gave it permanently to Chris.

The original Wal was very heavy and Squire eventually got a lighter replica made in Japan and donated the original to Hard Rock Cafe where it stands today in New York.

Other Prog musicians to have used triple-neck instruments include Led Zeppelin’s John Paul Jones and Jimmy Page (in their case 6 and 12-string guitars plus mandolin, manufactured by luthier Andy Manson).

Another triple neck guitar which is reasonably playable is Steve Vai’s white Ibanez (which he uses for performing ‘I Know You’re Here’) with a lined fretless 6-string at the bottom, a fretted 6-string in the middle and a 12-string at the top, but other guitars with three or more necks frequently tend to be oriented to add some show rather than actually contributing to the musical depth (such as Michael Angelo Battio’s Dean ‘Quad’ 4-neck guitar, the multi-neck guitars from Cheap Trick’s Rick Nielsen or even Steve Vai’s own older triple-neck ‘Heart’ Ibanez).

The Chapman Stick was created by Emmett Chapman in 1974. It consists of a long and wide fretboard where the musician taps with both hands. Several models have been produced with 8, 10 or 12 strings. A particularity of the Chapman Stick is that unlike in a guitar the lowest pitch string is located in the center of the fretboard.

Tony Levin was the pioneer in incorporating it to Prog Rock. Trey Gunn is another notable player.

The Warr Guitar is a hybrid of a guitar and a Chapman Stick. It allows playing it like a Chapman tapping with both hands but it also allows other common guitar techniques such as strumming, picking with a plectrum or slapping. Different version exist with different number of strings, typically 8, 10 or 12. Most players use a string setup like in the Chapman with the lowest pitch string in the center of the fretboard although some choose for a standard guitar setup with the lowest pitch string at the top.

Trey Gunn is the most notable Prog Rock player.

A similar instrument is the NS/Stick designed in collaboration by Chapman and Ned Steinberger (yes, the one from the headless basses and guitars), with 8 strings.

Don Schiff from the Rocket Scientists playing an NS/Stick



Another unique and curious string instrument is the Pikasso guitar made by luthier Linda Manzer for Pat Metheny. It has 42 strings. The main 6-string neck is used to play the background chords by tapping (it can control his Synclavier to produce keyboard-like or other sounds) and the melodies are played by plucking other strings as in a harp.


Pat Metheny’s Pikasso guitar



Always an experimenter, Metheny's most ambitious project to date is probably the Orchestrion. His fascination for mechanical instruments started as a kid with his grandfather's player piano, and the Orchestrion is the culmination of this fascination. It consists of a huge array of instruments which play mechanically driven by solenoids triggered by Metheny's playing on the guitar and loops / sequencers. So it's a one-man orchestra with which Metheny alone can play complete multi-intrument musical pieces in real time.

It includes piano, marimba, vibraphone, bass, drums, cymbals and various percussion instruments, blown bottles... He recorded the Orchestrion album with it in 2010 and more impressively he dared to tour live with it, with great success.

There’s not much to say about traditional acoustic drum kits and percussions except that in 1970’s Prog, size did matter. Again the ‘more is better’ philosophy seemed to call for a race for which drummer would have the biggest and most spectacular drum kit. As usual in Prog though, the great thing is that drummers did really take their skills to the limit to use effectively all those elements (unlike other music styles where sometimes a huge drum kit was present but hardly taken advantage of).

Double bass drums, more than one snare for different nuances, lots of toms, floor toms and cymbals were the norm. Drummers frequently complemented their drum kits with assorted percusssions, chimes, tubular bells, cowbells, gongs, bells, xylophones or glockenspiels…

Up to the present many manufacturers have made good drums but in the 1970’s the most appreciated brands were probably Ludwig, Tama, Pearl and Premier.

Regarding cymbals Paiste, Zildjian and Sabian were the most common.

It’s not the purpose here to go into any detail about particular drum kits, but if one deserves mention is Carl Palmer’s 1973 rotating custom drum kit made of stainless steel (its construction was sponsored by British Steel). The drum shells were of half-inch thick steel sheet and he asked jeweler Paul Raven to manually carve drawings on them using a dentist drill. It featured also the bell on its top which he famously played by pulling the rope with his teeth. The whole thing weighted 2.5 tons and several stages had to be reinforced to hold its weight and in some cases gigs had to be cancelled altogether. Although it was an acoustic kit it included a synthesizer processing the sound from the microphones (the famous effects in the Toccata solo), effectively making it the first electronic drum kit. He didn’t use it for long.

Rototoms (also spelled Roto Toms) are toms consisting only of a drum head held by a circular frame, without shell. Modern Rototoms were first marketed by Remo although the idea is derived from mechanisms applied to bongos and symphonic drums since as early as the 1920’s. The characteristic idea behind Rototoms is quick and precise tuning for melodic percussion. Normal tom heads need tuning by adjusting several tuning bolts in the perimeter of the frame (the number of bolts depending on the tom brand and diameter but typically around 6) and this makes precise melodic / chromatic tuning cumbersome and time-consuming. Rototoms on the other hand are mounted on a threaded central bolt and tuning is adjusted by simply turning the tom frame clockwise or counter-clockwise. This allows very easy and fast precise tuning. The sound of the Rototoms is not deep but rather trebble and percussive, ideal for starting a long fill and then switching to normal lower-pitch toms.

Bill Bruford was an early embracer but many other drummers have used them.


Rototoms in Bill Bruford’s kit



Tama released the Octoban toms in 1978 and although the name is Tama trademark the term Octoban has become generically used for this kind of toms, although they are also sometimes called tube-toms, quarter toms or Rata Toms which is the trademark from another manufacturer DW Drums.

They are deep shell, single-headed toms where the pitch variation comes from change in shell length instead of from change in shell diameter. The diameter is fixed and small (150 mm in the original Tama model).

The term Octoban makes reference to ‘eight’ and ‘octave’ since the original Tama Octobans range consist of a set of 8 different shell lenghts ranging from 280 to 600 mm tuned melodically covering one octave range (frequently drummers installed only 2 or 4 of them in their kits).

Simon Phillips, Bill Bruford or Stewart Copeland have used them frequently.

Although some purists may despise electronic drums, they offered a path for innovation in the 1980’s and several great Prog drummers have made excellent use of them including Neil Peart, Bill Bruford, Nick Mason or Phil Collins.

The first commercial electronic drum kit was the Simmons SDS-5 released in 1980, famous for the hexagonal shape of its drums which allowed positioning them in a honeycomb pattern, and Simmons continued releasing upgraded versions until its demise in the late 1990’s when mostly Roland (and to a much lesser extent Yamaha) took over the electronic drums market. A main problem of Simmons drums was that the response of the heads to the drummer’s sticks did not feel natural compared to acoustic drumheads, causing many drummers to not feel entirely comfortable and getting fatigue.

Roland released its first electronic drums called ‘Compact Drum System’ in 1992 and although technically superior to the Simmons in many respects, they still suffered from uncomfortable feedback from the heads to the drummer’s hands. Roland understood that this was the main problem for real success and set out to cooperate with Remo, the top manufacturer of acoustic drum heads, to find a solution. Together they developed a new head material they called ‘mesh drumhead’ which among other properties could be tensioned in the way traditional acoustic heads are tuned but without affecting the pitch, just in order to adjust the feedback to the drummer’s preference. This plus further innovations in the electronics culminated in the V-Drums of 1997. Since then Roland V-Drums have become the most popular electronic drums.

Originally the electronic cymbal sounds were rather poor and even today many professional drummers still use acoustic cymbals even when playing electronic drums, but the sound quality of electronic cymbals has improved a lot and is now fairly realistic.

Drummers who have tastefully integrated acoustic and electronic drums include Bill Bruford, Neil Peart or Nick Mason, sometimes having rotating kits which depending on the orientation are mostly an acoustic kit or mostly an electronic kit.

Perhaps worth a short mention is Led Zeppelin John Bonham’s Ludwig ‘Vistalite’ amber translucent kit, one of the first with the shells made of translucent plastic rather than wood or metal (or opaque fiberglass such as the Fibes). The Vistalites were released in 1972 (Fibes would also release their translucent or transparent version ‘Crystalite’ in 1977). Jethro Tull’s Barriemore Barlow had also a Ludwig Vistalite kit, in his case a blue one.

A quirky percussion element were the North drums first released in 1972, with the tom shells made of fiberglass and fitted with a single head. The toms and floor toms had a horn shape with the mouth directed to the front, the idea was to focus the sound projection towards the audience, and indeed these drums sounded very loud to the audience in front of the stage. However this characteristic was probably not too important in the professional world where drum kits were amplified anyway, and on the negative side their sound was not to everyone’s taste (someone described them as sounding like ‘banging on a big Tupperware’) and they were not easy for the sound techs to mic and mix.

Billy Cobham and Yes Alan White used them shortly but North drums never achieved much success, although a similar concept carried on in the Staccato drums released in 1977 and still in production, albeit also with little commercial success.

Another very special drum kit was the one played by Utopia’s Willie Wilcox around 1980 and nicknamed ‘Trapparatus’. It was a sort of ‘drumming capsule’ mounted on a frame and with Willie sitting in a car-style seat with his feet leaning forward. The bass drum and toms were very small and triggered electronic drum sounds. In some version he added a sort of exhaust pipes resulting in the whole kit resembling a custom motorbike.

Despite the iconic cover of Mike Oldfield’s debut album, tubular bells are straight vertical tuned pipes mounted on a rack and played with wooden hammers. The idea behind Mike Oldfield’s album artwork was a destroyed tubular bell.

Personally I would have liked the harp to be more prominent in Prog Rock since I love its timbre, but its appearances were limited. The best known use is perhaps by Yes Jon Anderson, who while not being a harp virtuoso produced some nice accompaniments for example in the middle section of Awaken. A more thorough use of the arp was done by the Swiss Andreas Vollenweider.

Queen’s Brian May is credited with playing the harp in some Queen songs but reportedly he could not really play it, he recorded each chord one at a time and then they were put together in the studio.

Bowed string instruments have also had their place in classic Prog Rock with bands like Gentle Giant using Violas, Cellos etc, the violin being probably the most prominently used, either amplified or in fully electric form. Key users of violin were Kansas Robby Steinhardt (later substituted by David Ragsdale), Eddie Jobson from UK and Jethro Tull, King Crimson's David Cross and Jean-Luc Ponty.

The archetypal flute player in Prog Rock is Jethro Tull’s Ian Anderson, but also Peter Gabriel made great use of it in early Genesis, as well as Focus Thijs Van Leer. Gentle Giant used also both flutes and recorders.

The Sax was most widely used as a main instrument in Jazz-Rock / Fusion than in standard Prog Rock but it surely deserves a mention. David Jackson from Van Der Graaf Generator is perhaps the most notable classic Prog musician dedicated to Sax, but Sax has also played an important role as soloing instrument, Pink Floyd’s ‘Money’ being a classical example. Ian McDonald and Mel Collins were also remarkable classic Prog sax players.

The Bagpipe, or its variants such as the bowel-blown Irish Uilleann Pipe, has had some presence in Prog since the days of early Mike Oldfield (or even earlier with bands like East Of Eden), and it has also been used by other Celtic-influenced bands like Iona, Mostly Autumn or the Prog-Folk of Alan Stivell.


Iona's Troy Donockley playing the Uilleann Pipe



The Talk Box, sometimes called  ‘the talking guitar’ was not very used in Prog but it has been occasionally used by David Gilmour (in ‘Pigs’ for example), Steve Morse and others.

While there were older similar devices the modern Talk Box was created by Bob Heil in 1973 and made popular mostly by Joe Walsh and Peter Frampton. In a Talk Box the sound signal from the guitar (or other instrument) amp is sent to the box which contains a small speaker driver connected to a plastic tube which goes up into the mouth of the performer, who has a microphone in front of him. The sound of the guitar enters the mouth where it is altered by the mouth’s shape and is then picked up by the microphone. By changing the mouth’s shape and tongue position the performer can alter the frequency spectrum and harmonics of the sound in different ways, and if he mouths words the resulting sound seems as if the guitar is talking.

The Vocoder produces a sort of robotic voice. The basic concept was originally developed in the 1930’s for encoding voice telecommunications but it eventually got also into the music world, with Robert Moog once again being one of its first developers for music in the late 1960’s.

The system’s input consists of a microphone (called the ‘modulator signal') and a ‘carrier signal' (usually a synthesizer producing any sound). The performer talks or sings into the microphone at the same time as he plays the synth, the spectral characteristics of the voice are analysed and mapped into the synth source sound, producing a hybrid signal between both, with the synth sound adopting some of the vocal qualities, and depending on the synth sound used sounding more or less as a talking synth.

Kraftwerk used it frequently for example in the ‘Autobahn’ album, other users have been Alan Parsons in ‘I Robot’, Pink Floyd (the barking dog in ‘Dogs’) or Mike Oldfield (for example in ‘Five Miles Out’).

Several manufacturers produced Vocoders including Moog, Korg, EMS or Roland.

Soon after the electrification of instruments, musicians and engineers learnt that the sound could be altered in different ways, sometimes unwantedly such as when an electric guitar sounded distorted if the signal gain was too high, sometimes by electromechanical means such as producing reverberation by inserting a spring between a transducer and a pickup in a spring reverb effect, or by purely electronic means, and gradually started to use these techniques in their favour in order to deliberately manipulate the sound.

Effects were mostly used on electric guitars although they gradually became commonly used with keyboards, basses and any other instruments.

Nowadays there is a huge range of effects available, Boss alone which is one the classic manufacturers has 56 different stompboxes in their line-up, and digital sound technology has pushed the boundaries of sound manipulation to the point where there are no limits anymore, so here I will mention only the most common single effects used in the 1970’s and 1980’s (which in any case remain the main ingredients of most modern complex effects).

Effects processors come in different formats, stompboxes are the classic single-effect pedals which can be connected in series and they were the most commonly used in the 1970’s, their main advantage being flexibility, you can combine them from different manufacturers and connect them in different sequences. Later on floor multi-FX pedalboards became popular because among other things they allowed storing multi-FX combinations as user presets which could be called at a press of a pedal switch. Rack-mounted effects can offer more sophisticated technology without the size limitation of floor units. Finally effects can also be built-in in the instruments themselves or amps.


Boss Stompbox Effects Pedals

The main classic effects can be classified by the kind of sound alteration they produce:

a) Distortion / Overdrive / Fuzz: all these work by increasing gain and clipping the ends of the wave amplitude making it more ‘square-wave’ and modifying the harmonics. Overdrive is a kind of mild Distortion which appears at higher volumes but sounds cleaner at low volumes. Fuzz is no so much based on adding gain but mainly on clipping the wave shape, producing that typical late 1960’s sound which while distorted, it does not sound ‘Heavy Metal’.

b) Reverb / Delay: These add echoes to the original sound. Reverb reproduces the natural echo of a spatial location where the sound waves are reflected by the walls and ceiling and gradually fade out. Delay is a more artificial echo where the sound is simply repeated after a time interval, once or multiple times (often the delay time is in the order of miliseconds, so it is not always obviously heard as a repeated note). A Loop effect would be another modern effect in this category.

c) Modulation effects: these would include Chorus, Flanger, Tremolo, Vibrato and Phase Shifters. These effects typically split the sound and to some of the signals alter slightly the timbre, pitch, phase or amplitude, and then recombine them all together, resulting in a richer, more ‘rippling’ sound.

d) EQ / Wah-Wah: these alter the equalization across the frequency spectrum. The Wah-Wah does so dynamically in real time at the musicians will using a potentiometer pedal. The Talk-Box could be included in this category as well.

e) Pitch-Shift: these would include Octavers, Pitch-Shifters and Harmonizers.

f) Volume-related: these would include Volume pedals, Compressors (which dampen the attack and amplify the sustain, smoothening the sound) and Noise Gates (which eliminate sounds below a certain volume threshold to reduce hiss and noise).

It is a very nice and impressive work, and I have not read a whole lot of it yet, but promise that I will.
I only have one concern here ... it's like saying that no one else EVER used any of these instruments and it's not true at all. Progressive music, or anything else, is not the only mode that is experimenting with instruments. In fact, most of them we can't even handle when we first hear it.
So s synth by this and that person is important, but by Carlos or Tomita it is not. I still think that this fits way better as the development of instrumentation in modern/rock/jazz music!
Does not fit as "progressive".

Hi Pedro,

I'm not quite sure what you are meaning. Obviously this article does not mean that all these instruments were only used in Prog! (please read the introduction). They were just instruments from that period, used in Prog as well as in many other genres at the time.

Then the title is WRONG!
It shold use "Popular Music", be it progressive, prog, jazz or anything else, it would fit your descriptions and magnus opus a lot better.
I, personally, find it offensive, that we think so little of everything else, and consider "prog rock" above and beyond many things because of an instrument, that was also used in every other category out there.
Your fascination with "prog rock" is bringing down the quality of your work.
This is maginificent work and study, and it would be even better if it showed how it IMPROVED ALL MUSIC ... instead of just "prog rock". Your entry and introduction is lacking because it is not about the title, either.

Re-quote of the introduction:

"For sure a more precise title for this article should be something like “An illustrated guide to some of the instruments frequently used in classic Prog Rock”, since the list does not intend to be comprehensive and all these instruments were of course not “Prog Rock instruments”, they were simply instruments of their period, used in Prog as well as in many other genres during that period, but the title is intended as a practical shortcut."

Whatever ... perfect for the magazine Rolling Stone, for the no-read nothing folks that only like pictures of stars.
In your case the instruments and pictures are the stars, because the content is mis-leading via the title!

Excellent archival document, Gerinski. Fascinating. And the title makes perfect sense for a prog-rock site; except, of course, for insufferable pr*cks with a bizarre axe to grind.

P.S. Might I suggest an addition under the acoustic guitar category? Ian Anderson's use of a Martin 0-16NY and other small bodied "parlour" guitars of the Martin New Yorker series. An iconic look and sound in the 70s.

Holy HELL...

...This just might be my favorite thread EVER.

While I don't own an actual mellotron, moog synth, or anything to that degree - I DID invest in a Roland GR-55 and GK3 pickup for my Ibanez RG Premium, and I haven't looked back! Also, Parker guitars are absolutely INSANE to play.

Anderson's Martin and his even smaller recent parlour added in the entry for acoustic guitars.

BTW, even having re-posted this long article splitting it in separate multiple posts, this thread is again suffering the strange problem that for some reason it does not shift to page 2, every new post gets added to page 1, I hope this does not cause loading problems for some people's browsers.
