RA Moog Modular IIIC...

Came into stock: Available from RL Music from January 2025

Servicing Status:  Subject to negotiation – see notes below.

Remarks:

We have decided to sell our 1968 RA Moog Modular IIIC – a 3-cabinet authentic, period correct all RA Moog modules system that dates from 1968.

This instrument forms a part of the RL Music Vintage Synthesizer Collection.  We have managed to keep some of the very best examples of Vintage Synthesizers that have come through our business over the last 22 years which we kept for our pleasure and interest. Whilst having a privileged position as a specialist dealer in this genre of equipment, we managed to hang on to particular instruments that were interesting and inspiring.  The RA Moog Modular IIIC is one of 40 instruments we have, but is the oldest and most historically important.

Due to the nature of such a rare and historic instrument, certain aspects of the sale will be unique, so we have tried our best here to fully represent the instrument with all the information we have available and honestly and acutely describe it. We encourage any prospective buyer to ensure you have all you need to make an informed decision to purchase it, so we are available to field any enquiry you may have, but we hope the following information covers all the pertinent details on this very special instrument.

Provenance:

We purchased this system via a VEMIA auction in November 2014 and collected it from the seller directly in the UK. The owner at that time of the sale had renowned synth-tech, James Walker, carry out a health check.  After we collected it from the seller in December 2014, we set it up and fully tested it and it was all working perfectly, but it has been in storage since so will need servicing.

We were told by the seller that they purchased it directly from Martin Newcomb’s Synthesiser Museum in 1999, so this RA Moog is featured in the Analog Heaven video production.  We have the original VHS cassette from this, but you can now find that on YouTube, link below:

https://youtu.be/IXaJnLsx1kg?si=ywAAFijJP1T6gsj2

The VEMIA Auction details for this RA Moog did highlight a modification carried out by Moog themselves, which we noted, so here are the details:

Moog (in the USA) updated some control components in the 901A Oscillator Controllers (not the Oscillators themselves) so that the 901A Oscillators can now tune to scale across the full 5 Octaves.

This modification does not of course alter the Oscillator tone. James Walker then replicated this modification to the other 2 x 901A Oscillator Controllers. Before this update, the RA Moog only accurately scaled across a single Octave, which is typical for these very early Moog instruments.

The other item of note from the VEMIA Auction in November 2014 on this system was that many of the yellow labels on the modules are no longer attached. The seller in 2014 did not know why these labels had been removed but it’s something that had been done during the lifetime of the instrument. Some modules have their yellow tags still attached, so you can see these from the photos of the reader of the cabinets below, but these are all 100% genuine RA Moog modules.

Historical Context:

The RA Moog Modular synthesizer, designed by Robert Arthur Moog in the 1960s, holds a seminal place in the history of music technology and electronic sound design. This essay explores its historical significance, cultural impact, technical innovations, and enduring legacy in detail.

Introduction

The advent of the RA Moog Modular marked a transformative moment in music. By making electronic sound synthesis accessible, flexible, and expressive, it catalysed the growth of electronic music and shaped numerous genres. Robert Moog’s groundbreaking work not only redefined how music could be produced but also introduced entirely new auditory experiences that resonated across artistic and scientific domains.

The Pre-Moog Era: Setting the Stage

Before the Moog Modular, electronic sound generation was largely confined to academic institutions and cumbersome, experimental devices such as the RCA Mark II Sound Synthesizer. These early machines were complex, immobile, and lacked the intuitive interfaces necessary for broader adoption. The idea of a portable and modular synthesizer—something that musicians could use in real-time performances or studio sessions—was virtually non-existent. The RA Moog Modular emerged as a response to these limitations, building upon the pioneering ideas of early electronic music visionaries like Pierre Schaeffer, Karlheinz Stockhausen, and Raymond Scott.

Technical Innovations

1. Modular Design

   The RA Moog Modular’s most groundbreaking feature was its modular architecture. Musicians could assemble a system tailored to their needs by connecting individual modules, such as oscillators, filters, and envelope generators. This flexibility revolutionised the approach to sound synthesis.

2. Voltage-Controlled Oscillators (VCOs)

   Voltage-controlled oscillators allowed precise and dynamic control of pitch, a cornerstone of analogue synthesis. The RA Moog Modular’s VCOs provided stability and tunability unmatched by earlier technologies.

3. Voltage-Controlled Filters (VCFs)

   The ladder filter design, patented by Robert Moog, became iconic for its warm, musical tone. This filter’s ability to sculpt harmonic content with resonance was a defining characteristic of the Moog sound.

4. Envelope Generators and Amplifiers

   The inclusion of envelope generators (ADSR—Attack, Decay, Sustain, Release) enabled nuanced articulation of sounds. Paired with voltage-controlled amplifiers (VCAs), these tools gave musicians unprecedented expressive capabilities.

5. Patch Cables and Signal Routing

   The use of patch cables to connect modules offered an intuitive, hands-on approach to sound design. This method inspired creativity and experimentation, making the instrument a powerful tool for composers and performers.

Cultural and Artistic Impact

1. Adoption by Pioneering Musicians

   The RA Moog Modular quickly found its way into the hands of forward-thinking musicians and composers. Wendy Carlos’s 1968 album *Switched-On Bach* demonstrated the potential of the synthesizer as a legitimate musical instrument, bridging classical music and modern technology. Similarly, artists like Keith Emerson, Isao Tomita, and Sun Ra pushed the boundaries of what the synthesizer could achieve in various genres.

2. Integration into Popular Music

The Moog Modular became a staple in the emerging psychedelic and progressive rock scenes of the late 1960s and 1970s. Bands like The Beatles, Pink Floyd, and Yes incorporated its distinctive sounds into their recordings, helping to propel the synthesizer into mainstream popularity.

3. Influence on Electronic and Experimental Genres

   Beyond popular music, the RA Moog Modular catalysed the evolution of electronic genres. Early pioneers of ambient, techno, and industrial music used the instrument to explore new sonic landscapes, laying the groundwork for countless sub-genres.

Educational and Scientific Contributions

1. Tools for Academia

   Universities and research institutions adopted the RA Moog Modular for teaching and experimental purposes. Its versatility made it an invaluable resource for studying acoustics, psychoacoustics, and sound synthesis.

2. Inspiration for Future Innovators

   The RA Moog Modular’s design principles inspired subsequent generations of synthesizer engineers. Its modular approach influenced the development of Eurorack systems and software synthesizers, ensuring its legacy in both hardware and digital domains.

Enduring Legacy

1. Vintage Appeal and Collectibility

   Today, original RA Moog Modular systems are highly sought-after by collectors and enthusiasts. Their iconic status and historical value make them prized artefacts in the world of music technology.

2. Reissues and Modern Adaptations

   Modern reissues and software emulations continue to honour the RA Moog Modular’s legacy. These products enable contemporary musicians to experience the instrument’s capabilities while benefiting from advances in technology.

3. Influence on Modern Synthesis

   The concepts pioneered by the RA Moog Modular—modularity, voltage control, and user-centric design—remain foundational in modern synthesizer design. From analogue revival instruments to digital workstations, the Moog ethos endures.

Conclusion

The RA Moog Modular synthesizer is more than an instrument; it is a cornerstone of modern music history. Its technical innovations, cultural impact, and enduring influence on music and technology underscore its importance as a transformative force. By bridging the gap between experimental sound and mainstream music, Robert Moog’s creation empowered generations of musicians to redefine the boundaries of sonic expression. As a symbol of creativity and innovation, the RA Moog Modular continues to inspire, proving its relevance more than half a century after its inception.

About Conservation & Servicing:

The RA Moog has been stored in our secure facility for 10 years, so will require servicing, but we are not having this work carried out in advance of the instrument going up for sale, the reasons for this are as follows:

Depending on your preference, will can have our Vintage Moog specialist synth-tech, Kent Spong at KSR, carry out the servicing work once we have completed the sale but we will not include restoration work to any of the modules or the wood cabinets as this historic instrument needs to be protected and conserved in its original condition.  This means any servicing would be carried out sympathetically and would clean and refurbish any parts as necessary but not replace anything unless it’s a critical requirement to ensure operational stability.

Some buyers may have a preferred tech do this work or in fact might prefer the Moog to be left untouched, so we have quoted a two-tier price option below so you can decide what you want to do.

If you would like us to have the RA Moog serviced by Kent at KSR, then the system will come with a 3-month warranty from us.  If you prefer to take the RA Moog ‘as-is’ and make arrangements to have any servicing carried out by your tech then we will not be providing any warranty on the sale of the instrument.

This RA Moog Modular came from the factory as a US 110V system, so we had not modified it in any way from the factory stock spec. All three cabinets operate on US 110V. We will supply two step-down transformers for use in the UK/EU in the sale. 

We do not have any original user or service manuals or cables with this system, other than the power cables for the cabinets. Accessory items like 1/4″ inch Patch-Cables and S-trig cables can be sourced from excellent suppliers like synthesizers.com in the USA – link to their website: https://shop.synthesizers.com/pages/cables

Packing & Shipping: 

We can ship this RA Moog Modular System worldwide, although the packing, shipping & insurance costs are not included in the sale price below, so are subject to quotation.  

We partner exclusively with established and trusted shipping providers that offer door-to-door service with online tracking. The goods will be fully insured for their sales value under a separate Marine Insurance Policy, the cost of which will be provided upon quotation. Please note that due to the significant bureaucracy involved in shipping overseas from the UK, there may be additional unforeseen administrative costs. These charges will be identified as a post-sale activity and passed on to the buyer at cost, ensuring that we do not profit from any logistics or packaging-related expenses.

We intend to have the Moog professionally packaged and palletised to ensure minimum handling and maximum safety during transport.  There would be some delays in getting the packaging solution quoted for our professional packaging partner (Neal Brothers Packaging and Export Packing UK).

Alternatively, UK buyers can collect the RA Moog from us in Reading, Berkshire, or we might be able to arrange a dedicated delivery in person, subject to the destination address & quotation. We are happy to discuss your requirements so please email us if you have any questions on the logistics and/or need a quote.

Moog System 15 Reiss...

Came into stock: Available for sale from RL Music as at 11th March 2019.

Servicing Status: This is a brand new instrument.

Remarks: We are offering up for sale, what we believe is the only opportunity to buy the last ‘as factory new’ Moog System 15 reissue left in the world. This Moog has never been touched since it left the factory in Asheville, USA. We never even took off the packing tape on the outer shipping box, so it genuinely qualifies as a mint condition instrument and as it came shipped from Moog.

There is #34 on the shipping box, so that’s possibly the serial/production number, but without opening it up, we wouldn’t know. The Moog System 15 comes included with all the documentation, certificate and cables ex-factory so a little time capsule already.

We purchased this brand new Moog back in 2016, and the intention was to keep it, unboxed, for use in the future, and to add to our Vintage Moog Modular collection. However, due to ongoing investments into the RL Music brand, including a new website we are having built, we now need to raise some cash, so reluctantly we will have to let this beautiful instrument go to another custodian.

There is plenty of information on the internet (and from Moog of course) about this beautifully re-made classic from the original Moog companies 1973 portable Modular line-up, and what a superb job of reproducing this they have done. It’s a hand-built instrument that oozes quality, heft and presence, with a ‘no expense spared’ approach to manufacturing it. We had the opportunity to Broker another System 15 reissue in 2019, and we can attest that this is most certainly not a low-budget clone, and sounds almost indistinguishable from the vintage original…bravo!

The pictures showing the front-panel and inner/retail box are for illustration only and our from our library of another System 15 reissue we sold for a client in December last year, so not the unboxed example we are selling now. The two pictures showing the shipping box and the ‘#34’ are of the actual instrument, or at least the outer-shipping-box with the modular synth inside its retail box, which we took in our storage unit, or Synth Storage Emporium, as we like to call it.

Of the only 150 produced there are no Moog System 15 reissues left in the world for sale from authorised Moog dealers. This sale is a unique opportunity to buy a factory-new machine that’s not had a hand touch it since it left the factory.

Whoever buys this Moog will be offered the opportunity (free of charge) for our synth tech, Kent Spong at KSR, to health-check to operational condition, but this will mean the packaging will need to be opened up to do this. This option is available, but we are not proactively going do anything to the Moog unless with strict instructions, and post-purchase, by the new owner. The Moog will be sold with our standard 3-month warranty.

Price: £12,990 GBP.

Availability: This Moog System 15 reissue is now SOLD, as at 17th April 2020.

We are Brokering this instrument for and on behalf of our UK Client.

Came into stock: Available from RL Music from 2nd December 2019.

Servicing Status: A full health-check by KSR will be carried post-sale.

Remarks: We’re both fascinated and excited to see one of the recently manufactured Moog System 15 reissues come though our Brokering Service, and unlike nearly all our usual opening remarks for vintage synths, this is in nearly new condition because it’s only 2 years old!

There is plenty of information on the internet (and from Moog of course) about this beautifully re-made classic from the original Moog companies 1973 portable Modular line-up, and what a superb job of reproducing this they have done. It’s a hand-built instrument that oozes quality, heft and presence, with a ‘no expense spared’ approach to manufacturing it. This is most certainly not a low-budget/cost clone, and sounds almost indistinguishable from the vintage original…bravo!

Only 150 of these System 15 reissues were produced, and this example is serial #123.

This System 15 was imported into the UK by my client from a Moog authorised US dealer, and was to be their first experience with using a modular synth, so quite a way to start. However, our client just didn’t gel with the format, and literally, after a single afternoons use, packed the Moog back up and put it aside. It’s a shame that this gorgeous machine didn’t resonate (pun intended) with our client, but sometimes that’s just how it goes, so we have been appointed to Broker it.

The System 15 works perfectly, but we will ask KSR to give is a full health-check before shipping/handing it to the new owner, but there are no concerns here about the operation.

Cosmetically, the System 15 is immaculate, as you can see from our own pictures, and the Modular comes with all the original documentation supplied from Moog, including a super hardback bound user-manual and serial number certificate. There is also a selection of 1/4“ jacks of varying lengths, S-Trig and V-Trig cables (pictured below) etc.

This Moog System 15 is currently set to operate on EU 220V, but it can be adjusted to work on any international voltage through the settings switch at the rear of the cabinet (pictured below).

Brokered through RL Music, it is being sold with a full 3-month warranty and can be shipped worldwide, and we can re-utilise the original Moog packaging for this as we have the inner retail-box (pictured below), and the outer export-carton as well, as well as the foam inserts, to protect the synth etc.

Demos are available by appointment only.

The health-check is carried out by KSR as a priority once the sale has been completed, and although it will delay shipping/delivery by a short time, we know from experience that customers are happy to wait.

Price: £10,500 GBP.

Availability: This Moog System 15 reissue is now SOLD, as at 9th December 2019.

Moog System 15 &...

We are Brokering this instrument for and on behalf of our UK customer

Came into stock: August 2016.

Restoration Status: KSR have already fully undertaken a full overhaul of the System 15 and 950 Keyboard in Nov 2016, so both items are ready for sale now.

Remarks: We have been given a unique opportunity here as this vintage original Moog System 15 & 950 Keyboard are owned by the son of the late Johnny Arbiter, who many of you will know, was the owner/operator (post 1990) of the famous Turnkey music retail business in London. Johnny died in 2003, and much of the collection of vintage keys that formed part of the Turnkey studio museum passed to his son, Dan Arbiter – our client.

We weren’t given a lot of detailed background information on this Moog System 15 & 950 Keyboard, but they certainly were in the Turnkey collection for some years (post 1990), although they have been in storage since around 2005, hence our client had commissioned KSR to undertake a full systems-wide overhaul of both instruments, to prepare them for sale.

Notes on the cosmetic condition:

Both units are in very good original condition. The original Tolex on the System 15 is in remarkable order with no tears, and the nickel hardware all showing a beautiful vintage patina. The 950 keyboard has it’s original wood cabinet which is in good condition, although does have a few signs of natural ageing and use, but the keys are undamaged, having an even colour. The module faceplates themselves are in excellent condition (as are the internal circuits), so we would rate both items as 9 out of 10 cosmetically – collector grade. Both items have not had any deeper cosmetic treatments (like re-tolexing or new wood cabinets etc.), so these would appeal to a more purist collector/enthusiast looking for a more authentic vintage look.

Notes on the restoration:

An IEC socket was fitted sometime during the lifetime of the System 15 to enable the system to be used in the UK, and although the power-supply has been reconditioned, it runs on US 110V (the transformer can’t be modified to run EU 220V). Originally, the system was supplied from Moog with the standard 3-pin US power-socket from the factory back in the 1970s.

All the 1/4 inch jack-sockets have been replaced with high-quality Switchcraft® panel mount sockets to improve connectivity. KSR implemented this upgrade as 40+ year old sockets can be very intermittent in connection, regardless of cleaning, and this can be very frustrating for users of voltage controlled/audio systems like these.

Our vintage Moog restoration expert, Kent Spong of KSR, undertook an extensive ground-up restoration on the System 15 & 950 Keyboard Controller between August and November 2016. Other than the items noted above in the ‘modifications’ paragraph, no components that effected the sound character of the Moog were replaced (or needed to be in fact). We retained the original knobs though as these are a major cosmetic component to the aesthetic of this authentic vintage instrument.

Configuration Top to bottom:

As was typical with these earlier Moog Music Inc. System 15, they contain a mixture of RA Moog and later Moog Music inc. modules. The earliest module in the cabinet is dated November 1973 but the majority are dated 1974, so we can arguably date the production of the system from around that time.
