“ARP 2600 SYNTH SERVICED
Selling my ARP 2600 as i need money for a project. The synth was fully serviceds in 2017 by Kent Spong: work included fitting new contacts, springs and bushings to the keyboard, plus general maintenance inc replacing caps and some knobs/switches. I also asked Kent to fit an additional long reverb tank as well as the short and install a toggle switch to alternate between the two. The central position of the switch bypasses both – please see last pictures. The switch can be mounted in the case – but i wanted to keep the 2600 original. so I’ve left this as an option for the potential buyer.
Manual and all cables are included. Sadly I’m selling as I need to fund other projects. ” Click here to visit listing on eBay

“I have an ARP 2600 & 3604-P keyboard owned and used By Jack Bruce of the band Cream.

I’m selling as my control room is rather small and I need the finance to put towards some other gear.

Both are in their original boxes and have ‘The Jack Bruce Band’ stenciled on the outside. I have had it refurbished so it is back in fully working order apart from one of the internal speakers isn’t working, I decided to leave it original instead of opening her up and replacing it. I have a certificate of authenticity from Jack’s family to prove it’s provenance. There is no handle on the case of the 2600. I have given the Tolex case a good scrub and it has cleaned up nicely.

Work Carried out by Synth Restore in Bedford by Adrian.

Oscillator1 and 2 were replaced.

Replaced some broken sliders and replaced some that were showing signs of age.

All sliders were cleaned and lubricated.

Replaced many of the slider tops, as almost half were missing.

Serviced the keyboard, and cleaned the key contacts.

Calibrated the oscillators, and filter.

Power supply had the power transistors replaced.”

“Prized ARP 2600, fully functional with original user manual and patch cords. This unit has been completely overhauled, every slider pots has been disassembled, cleaned and re-lubed by myself 2 years ago. This is an early 2600 circa 1973 that has the patent infringed Moog filter 4012. The tolex is in pretty good condition given it is 44 years old. The face panel is in impeccable condition, no scratches or wear. The cable between the unit and keyboard has been replaced with a DIN type connector for a more reliable connection.

2600, 3604, ARP @ 29 March 2017, Comments Off on ARP 2600 with ARP 3604 Keyboard

26003604 “FOR AUCTION: an original 1971 Tonus logo ARP 2600 semi modular analog synthesizer (model 2600P V1.0 according to discretesynthesizers.com, this is a pre-26xxx serial), complete with its original model 3604-P keyboard. I’ve owned and maintained this synthesizer for about 7 years, purchased locally from its original owner who had it in the back of his closet for years.

Condition: physically and electronically, this is among the nicest ARP synthesizers you’ll find from this era- even the Tolex on the synthesizer is in great shape (only the removable lids have notable peeling and I probably wouldn’t want to rely on them for heavy transport). Electronically, I initially had it restored by Greg Montalbano in Oakland (analogsynthservice.com) who, in addition to general restorative cleaning, also recapped the power supply, replaced the epoxy’d filter with the lower noise CMS 4012 and replaced the internal speakers with new ones purchased from the late Kevin Lightner. It has subsequently been maintained by Chris Hewitt / thisoldsynth.com who I had replace the epoxy’d VCO 2 submodule with a new CMS 4017; you can see his blog for the repair here: http://thisoldsynth.com/blog/2012/03/05/arp-2600-with-bad-vco/ . Both of the original ARP submodules that I’ve replaced will be included.

What’s included: Arp 2600 with keyboard and lids, original power cord, and cable that connects the keyboard to the synthesizer. Two Switchcraft Tiniplugs for shorting internal connections and a few gray patch cables to get you started patching the synthesizer.

What to expect: the synthesizer is in great condition but ultimately behaves like any synthesizer from the 1971– this is not a 2017 Moog Voyager, this will need time to warm up for the oscillators’ frequency to stabilize and the signal path is a little dirtier. The cable that connects the keyboard to the synthesizer is a little sensitive– it could be cleaned or replaced although you’re not going to notice this other than when you plug the two together. You will overdrive/distort the signal mixer if you run multiple VCOs/sound sources into it at too high of a collective volume– this is normal and I believe the CMS 4017 oscillator (VCO 2) outputs a hotter signal in general; you can back down the VCO levels to keep your tone clean or you can overdrive it by choice as with any mixer. The spring reverb is not isolated from the cabinet well at all– it is *very* sensitive to movement; both techs I’ve had work on the ARP have offered to isolate it but I absolutely love it the way it is, it is a gorgeous, messy reverb. I think the 2600 makes a great general spring unit, you can run a guitar or other signal right into the preamp. Ultimately, it’s in great shape but make sure you have a tech who can work on it should anything ever go wrong. It’s a heavy synthesizer and shipping will always be a real expense if you don’t have a local tech. Also– you can ignore the “Arpeggiator / Sequencer” part of eBay’s pre-populated product description, that’s inaccurate.”

2600 “The synth has remained in my private studio since returning from Phil and has had minimal use over the years.
This Arp 2600 is in full working condition with minor cosmetic blemishes.
The 3604 Keyboard is in great shape – bushings / keys play very well.
NOTE: there is one broken potentiometer cap on the Sample & Hold “rate” (see photo). This is due to a little-lite falling from a shelf.
NOTE: ebay lists “Arpeggiator” and “Sequencer” under the items features, obviously this is not the case.”

26003604 ” For auction is an ARP 2600 v3 analog synthesizer with case cover and the coveted copper-cased 4012 Moog-ladder-filter-type filter as well as an original 3604 keyboard with case cover, featuring tuning, scaling, and portamento controls. The auction includes the connector cable that connects the synthesizer to the keyboard, the original power cable, seven 1/8th inch patch cables, and a plug for the filter section to defeat keyboard scaling of the filter cutoff, if desired.

This synthesizer is fully-functional. It was just serviced and cleaned by a very competent tech, and the keyboard was re-bushed.

The jacks have seen a lot of use, and are, in high-traffic patch areas, somewhat loose. Repositioning the cable (of the type included) is often required when patching in the CV region of the filter. The cable that connects the synth to the keyboard is fully functional, but is loose enough in general that you might not want to do an Edgar Winters (although there are guitar strap pegs on the edges of the keyboard!). These issues are very minor, but I wanted to be clear about them.

The tolex on the synth, the keyboard, and their case covers is original, and has wear, some slight tears, and one big tear on the bottom (see pictures). All of the fasteners are functional, but they and the other metal outer aspects on the case are worn with some spotting. One of the feet is loose, but simply requires tightening from inside the case. The faces of the synthesizer and of the keyboard are in good condition, and feature original caps and knobs.

This sale is undoubtedly one I will live to regret. I bought this synthesizer in 2006, and it has been one of the best synthesizers I have ever owned. I have used it in countless recordings, and it has served me well. It has lived in my cool, dry, smoke-free studio, and has been treated with care and respect. I am only selling it because I need funding for a business venture.” Click here to visit listing on eBay

26003604 “I bought this as a collectors grade piece, but I just don’t use it enough to justify keeping it. It’s barely be used & sounds better then anything you’ve ever heard. There is 1 tiny flaw in the case, where it was bumped by another synth. The restoration work alone cost $4272.70USD. I’m including the power switcher from UK to USA voltage & the manuals.

Remarks: Although these are not rare by some vintage synth standards, finding an Arp 2600 in anything approaching even good condition is a real challenge in 2014. This is why we invest such a lot of time, resources and money into getting them restored to the highest possible level that can be achieved – a FULL cosmetic and operational project restoration!

This Arp 2600 comes with a 3604P keyboard controller, original Arp power cable, keyboard-to-synth cable, and runs EU 220V. The actual version is a 2600P V3.0, manufactured between 1972 to 1974.

Original Arp Filter for this model (un-encapsulated) 4072

VCOs are original (encapsulated) Arp 4027-1

VCA is (encapsulated) 4019

The restoration work we invest into the Arp 2600 is extensive (what we term Total Restoration). The work includes re-Tolexing the cabinets & lids, stripping the panels to bare metal and having them professionally repainted and screen-printed. We have all the sliders and sockets deep cleaned and the whole synth is electronically restored including the a PSU rebuild/re-cap etc. In addition, we have fitted a brand new 17 inch Acutronics Reverb Tank, and a full set of brand new slider caps.

This RL Music prepared Arp 2600 is over 40 years old, and is in ‘as-new’ condition. On average we spend around £2800 GBP just in restoration costs for these models (synth & keys), so there is no equivalent in terms of quality offered by any person, or business, in the world. If you have been looking to own the ‘perfect’ Arp 2600 then look no further. These highly pro-restored examples are all sold with a full 6 months warranty.” Click here to visit listing on eBay

260036004 “This ARP 2600 and 3604 have been extensively restored cosmetically and electronically. This 2600 look and sounds like new. Extensive work was put in to this restoration and the labor costs alone would exceed $5000 at our shop. Ebay only lets us post 12 photos. For a lot more photos, check out the New England Analog Facebook page. There are some before and after pics, and a lot of photos of the restoration process. Here is a list of the work that was done on this synthesizer:

ARP 3604 Keyboard:
All old rubber Pratt-Read key bushings were replaced with new bushings
Sample and hold capacitors replaced with WIMA capacitors
CV memory opamp replaced
Aftertouch sensor added to keyboard
Keyboard Bus bars (3 total) replaced with new ones
Keyboard leveled, lubed, calibrated
New tolex and hardware
Cinch Jones connector replaced with 8-Pin DIN

ARP 2600
Case stripped, repaired, re-tolexed
All case hardware, latches, handles, rubber feet, screws, corners, finish washers replaced
Recessed 8-Pin DIN jack added
Aftertouch circuit (0-10V, 10V=Maximum aftertouch pressure) added
Old power supply removed and replaced with a Power One linear supply (Much nicer than original)
All tantalum capacitors replaced with new tantalum capacitors
All polarized capacitors replaced
Opamps in audio signal path upgraded
Reverb driver circuit completely rebuilt down to the resistors (Now it is dead quiet even when driving the reverb tank at 100%)
Reverb tank replaced with 17″ Accutronics reverb tank.
Original 4019 VCA module replaced with modern clone (NEA4019) which uses very high quality matched SSM2220 and SSM2212 transistors as well as a Burr-Brown output opamp.
Power indicator lamp replaced
Unit fully calibrated

Currently, the aftertouch voltage output (0-10V) is connected to the bottom jack on the multiples. We can put a separate aftertouch jack(s) wherever the buyer would like it. The ideal spot would be to place the new Aftertouch Out right above the multiple jacks. This can be discussed with us privately.

All various electronic problems with unit have been addressed and solved. ” Click here to visit listing on eBay

The synth is fully functioning and sounds amazing. It could however probably use a service at an appropriate point. A few of the sliders are a little noisy and will need cleaning or replacing.

The unit has been tinkered with in it’s past to add in some additional pots and switches. They actually add some really useful functionality. Each oscillator has an extra pot which provides extra fine tune which is really useful when dialling in any syncing between the oscillators. Each oscillator also has a 3 position switch that switches the oscillator octave. Very useful for building stacked oscillators quickly rather than using the frequency slider. On the ADSR you can see a switch over the attack and release sliders. The attack switch doubles the attack range and the release switch half the release range.

Overall the condition on the tolex would be best described as ‘well used’. Understandable for its age. I would suggest this is not an example for the purest synth collector but rather a great example of a 2600 to be played and used. The modifications greatly help the playability of the synth. I have found them really useful over the 5 years I have owned this wonderful synth. I will be very sorry to see her go.

Some etching below each serial number plate on each unit (can be seen in photos).

New power cable and 6 Pin Cinch Jones Keyboard Connecting cable recently purchased and included.
Jones cable is 10 ft. long.

Synth. and Keyboard were purchased new from an educational facility here in Wisconsin back in the ’70’s. Was used for educational purposes/educational performances/etc.

Unit recently brought to a technician who has worked with ARP’s and similar for the past two decades. I had him thoroughly test the unit – testing each aspect to see its current performance. Tech played the unit for about an hour in my presence the entire time.

ALL OSCILLATORS, AMPLIFIER, ENVELOPES WORKED EXACTLY AS IT SHOULD AS THE TECH WAS PLAYING/TESTING THE UNIT. BOTH INTERNAL SPEAKERS SOUND NICE. OUTSOURCING AUDIO TO AN AMP SOUNDED VERY NICE AS WELL. THE ONLY COUPLE THINGS THAT THE TECH SAID THE UNIT COULD BENEFIT FROM WAS THAT THE KEYBOARD BUSHINGS COULD NEED A REPLACING (BUT STILL PLAYABLE, KEYS WERE A LITTLE ‘CLICKY’) AND THAT SOME OF THE SLIDERS NEED SOME CLEANING BUT NOTHING MAJOR. BUSHING SERVICE WAS QUOTED AT RIGHT AROUND $250. FURTHERMORE, UNIT IS IN TUNE.

****NOTE: THIS WAS ONE TECHS OPINION/COMMENTS AS HE PLAYED THROUGH IT FOR A WHILE. I PERSONALLY AM NOT WELL EDUCATED IN REPAIR/SERVICE OF THESE OR ADVANCING PLAYING. POTENTIALLY SOMETHING FURTHER COULD NEED SOME ATTENTION – JUST UNSURE.

SIMPLY DUE TO AGE, SELLING UNIT ‘AS IS’ WITH NO RETURNS.

Both the synth and keyboard have the storage covers that stay connected with the metal latches. There is one metal latch on the synth that is broken, however the others hold the cover on nicely and both can be transferred by the carrying handle.

One slider cap missing on one slider in the bottom middle of the synth board.” Click here to visit listing on eBay

used arp 2600“I am not a synthesiser expert though my friend is a musician and music producer, so he will be able to help with some questions, although you’ll have to bear with us on the more technical aspects of synthesiser programming.



The brain and keyboard have just been returned from a full service by Andy Jury at Synth Prof and so are operating perfectly and are covered by their three month warranty dated 01/10/14. 


As you can see it packs down into two protective cases and comes with the original 2600 manual, recet repair receipts, service history dating back to 2011, mains cable, interface cable (keyboard to brain) and a large collection of patch cables.

It is in fantastic condition for it’s age and though it is not perfect cosmetically (various nicks in the tolex, a modification to the side of the case where the mains socket has been replaced/updated and two small melt marks on two keys of the 3604-P) none of these hamper its performance in any way and are very minor when taking into account the vintage nature of this instrument.

The serial number is 2601-0*5*.” Click here to visit listing on eBay

Arp 2600 model 2600P with 3604P keyboard and original manual.

This 2600 has the famous Arp 4012 “Moog copy” filter inside.

Classic and highly desirable music instrument. Has become exceedingly rare, people buy them and keep them!

Manual is in good condition, some scribblings inside but perfectly usable.

Overall this instrument is in very good condition but shows some sings of use/age.

The front panel and the keyboard look smooth, key action is good.

Both the original cover for the keyboard and the instrument are included with the sale.

Tolex shows sings of use and has some minor damages but nothing extraordinary.

Its a old synth!! Has seen some life i guess, please accept that it is from early 1970’ies.” Click here to visit listing on eBay
