Roland System 700

Came into stock: Available from RL Music from 16th April 2018

Restoration Status: KSR will commence full restoration on the system from w/c 23rd April 2018. The (estimated) time to completion is between 5 to 7 weeks.

We probably don’t need to make much in terms of introduction here, but with there only believed to be 40 System 700 ever made, then you will appreciate this instrument was scarce even when it was in manufactured during the period of 8 years from 1976.

As electronic musical instruments go, this is considered by many to be the Holy Grail of synthesizers, and is without any doubt, amongst the very best designed and built analogue modular synthesizers ever made. It’s not for us to just extol the virtues of such an outstanding instrument because the worlds most accomplished synthesists have proven the capability of these beautiful creations in their music, so we’ll just talk here about this particular example that’s available for sale.


This System 700 has only very recently been purchased from its original owner in Japan. The owner purchased it new from Roland and had it kept in their home all that time, and although they could not recall the exact date it was bought, it was certainly around 40 years ago. The incredible instrument has been imported directly into the EU from Japan and is now being offered by RL Music for sale.


Upon arrival at RL Music, we checked over the system and found it to be 100% intact with all the controls, ancillary hardware (including all lids), knobs, sliders caps, switches, keys, cables etc., all to be present and correct. The condition of the Tolex covering on each and every Block is excellent, and the anodised control surfaces & screen print on each individual module to be superb, with only minimal wear…remarkable!

There is a small scuff on the sequencer panel, and some of the anodising on certain modules has oxidised due to age, but otherwise, this is a close to perfection as is possible, and the dream of most of us to own.

The functional condition of each and every function of the modular system has not yet been tested as Kent Spong of KSR will be undertaking a full restoration on this shortly, but we have checked it at a higher level and are satisfied this machine lives and is awesome!

The restoration will entail a full strip-down and rebuild of every single module from scratch, so several weeks work of meticulous cleaning, testing, calibrating and power conditioning. More on the restorative work will be reported on once this has been completed, but Kent at KSR has a lot of experience working on the Roland System 700 technology, so we know this instrument will be in superlative condition once completed.


This is a standard configuration system, so has not been modified from its original factory specification:

Block 1-Main Console (sn: 590069)
This is the Heart of the System, and it contains all the basic modules necessary for a professional system. It has 3 x VCO, 2 x VCF, 2 x VCA, 2 x LFO, 2 x ADSR EG, Noise, Ring Mod, Voltage Processor, S/H, Envelope Follower, Integrator (Lag Processor), Mixer, 2 X 5 multiples, Headphone Monitor Module, and an Output Module, which includes Stereo VUs, a six-position test-tone, Phase Shifter, Spring Reverb, and voltage controlled Panning. Most common module connections (power, cv, gate) are made internally for easier patching.

Block 2 – Keyboard Controller (sn: 630116):
The 61-key two-voice Keyboard with Portamento and Pitch-bend controls.

Block 3 – Sequencer (sn: 800097):
This offers 3 x 12 step sequencer with Pulse Shaper, Clock Oscillator, and Series / Parallel output sections – considered one of the best analogue sequencers ever made.

Block 4 – VCO Bank (sn: 800002):
6 x VCO, a dual ADSR envelope generator, LFO, Sample and Hold, 2 x 5 Multiples, and a small Mixer.

Block 5 – VCF/VCA Bank (sn: 800003):
2 x VCFs, 3 x VCAs, 2 dual ADSR envelope generators, 2 x 5 Multiples, and a Gate Delay.

Block 6 – Interface/Mixer (sn: 780089):
A Frequency-to-Voltage Converter Interface, a VCA, 9-channel Audio Mixer, and a Multimode Filter.

Block 7 – Phase Shifter/Audio Delay (sn: 800001):
A 2-channel Phase Shifter and a 2-channel Audio Delay, 4 input Analog Switch, Envelope Follower, Integrator (Lag Processor) and a 2 x 5 multiple.

The System 700 is a professional grade instrument, with a price tag to match back in the late 1970s, and recent specialist auction prices show that these have risen very sharply in price. Demand has always been very high for anything System 700 related, either in the Lab Systems or separate Blocks being sold, but finding a full system is exceptionally rare.

Post-restoration by KSR, this System 700 will be sold with a 6-month warranty and will be ready to ship worldwide. A quote for custom packing (by us), shipping & insurance to get it to you will be produced upon request. Delivery by us (in person) is possible for most UK destinations – prices subject to address.

This beautiful behemoth of a synthesizer runs on 110V. We are not supplying any 1/4” jack audio cables with the sale, and unfortunately, the original owners manual was not supplied to us, but we do have a high-quality version in PDF which we will include in the sale.

This is one serious music machine and words simply can’t describe the power and potential for infinite sound creation possibilities. There is such a lot to say about this legendary and beautiful modular system but we just haven’t enough room here on our website so please call or email us to discuss your requirements.

Moog System 55

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

Came into stock: Arrived at RL Music in April 2017

Restoration Status: A full cosmetic and operational restoration by KSR has already been carried out (completed in 23rd August 2017), so this Vintage Original System 55 is ready for sale now.

Remarks: We have been granted a unique opportunity here as these Vintage Original Moog System 55 (with RA Moog 950 Keyboard & Garage) are super rare instruments, and highly sought after. We weren’t given a lot of detailed background information on this system other than the last owner purchased it from a well known Moog collector in Italy several years ago. The Italian musician/collector used this system as a part of a larger Moog Modular set-up, which explains why the configuration is not quite late 1970s factory stock.

Our client (the current owner) had commissioned KSR to undertake a full system-wide overhaul of the entire instrument, to prepare it for sale. The restoration included refinishing all the cabinets as well, so the fit & finish on this 40+-year-old Moog is sublime, and of course, it works flawlessly.

This is THE mother of all synthesizers and although there are a plethora of analogue instruments in modular format to choose from these days (which is wonderful), nothing will hold the mystique, power and sheer collectability of an original Moog. These Vintage Moogs come with very strong & proven investment potential, so aside from being outstanding music instruments, they keep giving in other ways also.

The System 55 was the last of the great “walls-of-Moog” and this system being from around 1976, represents the most stable and reliable in terms of module build versions. This particular System 55 has clearly been lovingly cared for, for 40+ years.

Notes on the cosmetic condition:

All cabinets and control surfaces on the main synth sections are in excellent and original condition. The RA Moog 950 keyboard & Garage have their original wood cabinets which are also in excellent condition, although all the cabinets do have a few signs of natural ageing and use, however, the keys are undamaged, having an even colour. The module faceplates themselves are in excellent condition (as are the internal circuits) but there are inevitable signs of some wear from around the locating screws, although this is something we would expect to see in a modular system of this age.

The top cabinet did not come with a rear-enclosure board fitted. Many modulars of this age do not have rear-covers, but KSR have offered to manufacture and fit one if the buyer of the system would like one fitted. There would be no charge for this, but the top cabinet would need to go back to KSR to have that carried out.

We would rate the whole system as 9 out of 10 cosmetically – collector grade.

Notes on the restoration:

An IEC socket was fitted as standard on these late 70s systems. The power-supply has been completely reconditioned, it runs on US 110V or EU 220V, although set on EU 220V whilst here in the UK of course.

All the 1/4 inch jack-sockets have been replaced with high-quality Switchcraft® panel mount sockets to improve connectivity. KSR implemented this upgrade with the owner’s permission 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.

Each and every module and been tested, cleaned & calibrated, and where necessary, any decoupling (power regulation) caps replaced. The 950 Keyboard has been stripped and completely overhauled, with every key cleaned, and the key-bed & contacts cleaned.

All Cinch-Jones S-Trig connectors cleaned/deoxidised.
Wiring loom integrity checked.

Other than the items noted above, no components that affected 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.

Thousands of pounds have been spent on the restoration work which has taken Kent Spong of KSR, over 3 months to complete.

Module configuration as follows:

Top Cabinet
1 x 914 Fixed Filter Bank
1 x 992 Control Voltages
1 x 904A Low Pass Filter

Arp 2600C

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

Came into stock: Arrived at RL Music on 15th February 2018

Restoration Status: A full service by KSR has already been carried out (completed in February 2018), so this Arp 2600 is ready for sale now.

Remarks: We have a remarkable opportunity for you to own a true one-off example of what is considered to be one of the finest vintage synths ever made – the Arp 2600, but with a lot of extra added value. The ‘C’ is for Custom!

Standard Arp 2600 features: Semi-normalised – 3 VCOs (4027=1), 4 pole Lowpass VCF (4012), VCA, Ring Modulator, 2 EGs, sample & hold Noise, Mic Preamp, Spring Reverb, Voltage Processor and Four Octave Keyboard….the list goes on. This is an Arp 2600 (2600P V3.0). There is no Keyboard controller included with this sale.

What is different about this Arp 2600?

Wood Cabinet: As you can see from the pictures below, our client decided to have a custom Walnut cabinet made (by Lamond Design) in 2017 for the synth, replacing the original plywood/tolexed case. the cabinet was hand-made by Ross Lamond and finished (stained and waxed) by Kent Spong at KSR. The results are sublime, and as far as we know, this is unique…stunning! All the metal hardware was also replaced with the black anodised fittings to the case. KSR spent 4 days carrying out this highly skilled work.

Metal Control Panel: The main control panel has been stripped, repainted and screen printed to produce an ‘as new’ finish. This is expensive and very time-consuming work and the panel restoration was completed at the end of 2017. KSR had to strip down the Arp completely so the panel could be sent away for the cosmetic treatment, so the synth has been fully rebuilt by KSR and serviced – around 50 hours work in total (not including the cabinet refinishing work).

Modifications by CMS (Phil Cirocco): Our client commission CMS in the USA to carry out some mods on this Arp 2600, so here is a list of what’s been done to this synth:
>Variable octave switches and pot for all 3 VCOs, range of 2 octaves
>Sync switches 2-3, 3
>17″ reverb tank upgrade
>1/4″ input and outputs (main in/outs)
>Upgraded PSU – running EU 220V
>All sliders were chemically cleaned and lubricated, VCO trimmers replaced
Our client spent over $2000 USD with CMS for these modifications in 2017 – to find out more about CMS then please click this link:

Our client has invested thousands of pounds on having this Arp 2600 prepared to such a high standard and it certainly stands out as a unique and stunningly beautiful example. The sales price does reflect the investment made and quality of the finish, the technical preparation by two of the industries leading vintage synth specialists, and finally, the warranty sold by RL Music on this instrument. We think it’s fair to say that there’s a fair amount of extra value with this machine.

This custom rebuilt Arp 2600 operates on EU 220V. it’s sold with a 6-month warranty. Included in the sale is proprietary Arp power-cable, and we will also include a PDF copy of the user manual.

Price: £8500 GBP.

Availability: This custom rebuilt Arp 2600 is available for sale now.

Moog System 12

‘Rare’ doesn’t come close to describing how few and far between these vintage original Moog Modulars are these days, and owners are simply hanging on to them whilst all the reissues from the new Moog company are making their transition into the market. The fact remains that savvy owners truly appreciate the historic value of these genuine ‘Bob Moog’ manufactured instruments, and why this lineage is what really counts at the end of the day, both emotionally, historically and commercially speaking – certainly in investment terms.

So why are we selling this beautiful Moog Modular System 12?

Well, this example comes from the RL Music private collection and has been fully professionally restored in 2015. We are releasing this for sale as we already own 3 other vintage Moog Modulars, and would like to raise some capital for some new vintage modular projects we have planned for this year, so here is a golden opportunity for someone looking to own a genuine piece of synthesizer history.

There is a considerable volume of material written about the amazing Bob Moog and his ground breaking synthesizer designs from the 60s and 70s. Also, we all appreciate the outstanding sonic capabilities of these amazing instruments and why Bob Moog’s synthesizers changed the world, but to cut to the chase, here are the facts about this System 12 we have for sale.

Background history that we have:

The Moog System 12 unit has serial # 1039 and features some early ‘RA Moog’ modules from the time the Moog factory was located in Trumansburg, NY, and some modules with the later ‘Moog Music used after the move to Williamsburg. This is actually quite normal for these models as the assembly/manufacture date was around the early 1970s, so there would have been some RA Moog modules still available to use when assembling these systems. This puts an approximate age on this System 12 at 44 years old…not bad!

In the 1970s this System 12 belonged to the synthesist Jan Ternald of the Swedish psychedelic rock band Älgarnas Trädgård. After that, it ended up for unknown reasons in a small demo studio in Stockholm where it was left unused and forgotten until it was found and purchased by the last owner in 1984 (of whom RL Music purchased it from in 2015). It was mounted in custom-made flight cases in 1989 to allow touring and live performances. The original live setup also included two Mini Moogs, both stripped of the keyboards and mounted as rack modules, and an oscilloscope + a guitar tuner.

The system was then located in a recording studio in Stockholm, Sweden, and used in numerous productions until 1999. The last owner bought the System 12 to London In 2010 where it was located in the studio of an audio design company – it was continuous use (and professionally maintained) until it was sold to RL Music in 2015.

Modifications of note:

The two 921B oscillator modules have at some time prior to 1984 been modified by replacement of the original potentiometers with 10-round precision pots.

An IEC socket was fitted sometime during the lifetime of the System 12 to enable the system to be used in the EU. The power-supply is rated to 220V, so it’s possible it was produced for the EU market by Moog, but we’re fairly sure that these systems were supplied with the standard 3-pin US power-socket from the factory back in the early 70s, so the IEC socket is more useful for EU users.

The System 12 arrived at RL Music without its original lid (lost over the years), so we have had a new one manufactured by Lamond Design, and then the whole system has been re-tolexed, with new nickel-plated hardware fitted by KSR in the UK to finish off.

All the 1/4 inch jack-sockets have been replaced with high-quality Switchcraft® panel mount sockets to improve connectivity. We decided to implement this upgrade as 44-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.

Configuration Top to bottom:

903-A Random Signal Generator (RA Moog)
907 Fixed Filter Bank (RA Moog)

Restoration notes:

Our vintage Moog restoration expert, Kent Spong of KSR, undertook an extensive ground-up restoration on the System 12 during 2015. Other than the items noted above in the ‘modifications’ paragraph, no components that affected 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.

We will service this System 12 prior to shipping to the new owener, so please expect a hort delay of up to 2 weeks post-sale before it can be shipped out.

This Moog Modular System 12 is sold with a 3-month warranty and mentioned above, runs on EU 220V. We will include a selection of (used) 1/4 inch jacks with the sale if needed, but we do not have any spare cinch-jones cables, although can supply these from new here –

We will ship this Moog worldwide, so please ask us for a packaging & shipping quote for your preferred destination address.

Price: £12990 GBP.

Availability: This Moog Modular System 12 is availble for sale now and can be reserved on deposit (20%).

Rhodes Chroma

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

Came into stock: September 2017.

Restoration Status: A full service by KSR has already been carried out (completed on 11th October 2017), so this Chroma is ready for sale now.

Remarks: We’re are delighted to be able to offer you this rare Rhodes Chroma from our current stock list. This particular example being customer-owned is in very good and all original condition throughout.

This customer owned machine does NOT have the CC+ CPU upgrade so is priced accordingly, but the restoration work we commit to in preparing these machines for sale remains the same regardless.

This particular example came to us from a UK customer. The Chroma had been owned & used by their family member – Kwame Kwaten from D-Influence, and he played it on Funky Times, Hypnotise and Hold On. D’Influence is a British production team and acid jazz band. You can hear these tracks in the following links (audio only): Funky Times Hypnotise Hold On

The Chroma needed a full overhaul, which KSR has meticulously carried out, and additionally treated all the cosmetics like the (lighter coloured wood grain) wood cabinet and other surfaces. The Chroma’s laminate front-panel is in very good condition across the main control surface with only some minor cracking showing around the left-hand side screw-points (see pictures below). The now re-finished wood cabinet itself is in great condition, and shows a nice aged patina, with only the front left-hand corner with some damage of note.

You can see for yourself from the pictures we took (below) that the cosmetic condition is remarkable for a 35-year-old instrument, and we would grade this as “very good original condition – 8.5 out of 10 cosmetically.’

KSR, our vintage synth restorers, have gone through the entire system in great depth on the Chroma to ensure everything is 100% perfect operationally. At some point in the synths life, a heat-sink was added to the rear of the instrument – this is actually not such a bad thing to have, and had been implemented well.

The patches already loaded onto the synth are really nice as well and show the current owner (our client) has a deep understanding of how to properly programme these beautiful sounding vintage synths.

The Chroma is a very well loved and supported vintage model within the synth community. Chris Ryan has an excellent website dedicated to the model which has been an excellent source of knowledge and support generally:

This Rhodes Chroma is sold with a 3-month warranty and operates on EU 220V. User & service manuals can be sourced from the website as mentioned above. This Chroma is also supplied with its original dual-pedal controls (pictured below).

Price: £6500 GBP.

Availability: This Rhodes Chroma is available for sale now.

Yamaha CS70M

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

Came into stock: September 2017.

Restoration Status: A full service by KSR has already been carried out (completed on 11th October 2017), so this CS70M is ready for sale now.

Remarks: We’re excited to be able to get hold of this really lovely condition CS70M as they really are quite magnificent synths for a whole number of reasons. These were proper old-school designed hybrid digital/analogue systems made between 1981 and 1984, and it wasn’t long after these came out that the DX7 was introduced, which seems hard to believe really.

The CS70M has for many people been overlooked, or perhaps overshadowed by it’s bigger brother – the CS80, but this instrument has ascended in popularity among aficionados, and we know this synth is highly sought after by those who truly appreciate it.

6 Voice, dual channel (stereo), aftertouch, 30 memories, ring-mod, chorus & Leslie effects, lowpass, highpass, and bandpass VCF, fully programmable and with a 4 channel polyphonic sequencer etc.

Those in the know will already tell you that this is one of the finest analogue polys ever made and a work of audio art in its own right. It shares most of the same technology as the CS80 and many of the characteristics and tonal qualities as well. The other big ‘Hello’ is also the fact you can get really close to the CS80 sound for a lot less money…this makes it even more appealing considering the price.

The UK owner we are selling this magnificent machine for has owned it for over a decade and the synth has been in regular use during that time, with periodic maintenance carried out to keep it in top workmen order. MIDI has already been retrofitted to this CS70M, which adds a lot of value when integrating into a modern studio setup.

The cosmetic condition of this example is extremely good overall with only light user wear & natural aging to the control surfaces. The faux wood laminate cabinet it in very good order with only a couple of spots where this has been worn. We would grade this is “very good original condition – 8.5 out of 10 cosmetically.’

Operationally, our trusted ‘Yamaha CS Series’ restoration experts – KSR have already carried out a full service on the CS70M, so it’s 100% perfectly working and ready for its new owner.

There are a few demos on YT of these but we like this rather ambient-noodling one from ‘MoreAnalog’ because it demonstrates nicely how the CS70M has the CS80 vibe we are talking about:

This CS70M is sold through RL Music with a 3-month warranty and can operate on US 110V or EU 220V. Also, we can supply a PDF photocopy of the user manual, and of course, the proprietary Yamaha power-cable.

Price: £6990 GBP

Availability: This CS70M is available for sale now.

Korg PS3200

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

Came into stock:  3rd March 2017.

Restoration Status: KSR to service once sold, and prior to shipping to the new owner. This PS3200 is in perfect working condition, but the servicing work is standard on all our vintage synths for sale, although it is more akin to a ‘health-check’ on a instrument of this fine condition.

Remarks: We are delighted to present a very rare opportunity to own a true vintage classic – the Korg PS3200. Our client has not owned the Korg for more than a few years, but it has been well cared for in their own home studio during their ownership. Prior to this the Korg was owned by UK synth collector. The cosmetic condition of the control panels & original wood-veneer cabinets for both the synth & the PS-3010 48-key Polyphonic Keyboard Controller are very good, with only minimal wear for an instrument of this age, and operationally it’s perfectly working. The PS3200 has clearly been very well looked after throughout its 40 year life, and likely regularly serviced as well, although we will carry out a further service on the synth for the new owner.

A couple of items of note:
There is a the non original knob on the PS-3010 Keyboard. The original Korg potentiometer is intact, so we can only assume at some time in the past, the large Korg control knob has been lost and replaced with the one you can see in the pictures below. Also, the battery cover at the rear of the synth is missing. Not huge problems in the scheme of things, but we’re just noting these for full disclosure.

The PS3200 is a fully polyphonic, 16 memory semi-modular system incorporating divide-down technology driving 2 VCO’s and micro tuning ability. The technical specification aside, this instrument defines the word “ambient” and has the most wonderful warm, rich and characterful sound that any vintage polysynth can deliver….a truly unique machine.

The semi-modular nature of the PS3200 provides some fascinating routing options for “polyphonic” sound design, and the remote keyboard offers a number of performance features within the CV/Gate domain.

This PS3200 operates on US 110V, but comes with a EU 220V converter – it will be sold with a 3 month warranty. Included with the sale is the original PS-3001 60-pin locking connection cable, and of course the proprietary power-cable. We will also include a PDF copy of the user manual.

Sales Price: £10900 GBP.

Availability: This PS3200 is available for sale now, and can be reserved on deposit (20%).
