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

” Ugh. It’s killing me to have to have to sell her. But recent events have deemed it necessary. You’re bidding on an ARP 2600 (2600p V 3.0 if you’re super geeky) with keyboard. Only had 2 owners. Unfortunately it’s spent many years in basement studios. So the case has some wear but the condition of the board is FANTASTIC! Both speakers work. The great Arp reverb is working as well. Some of the sliders have some slight static but overall sound is great. The biggest issue and one I’ve had for over 20 years, is the keyboard doesn’t seem to work. Not sure if it’s the connectors or the wire but I’ve never gotten it to fully work. I usually patched in my Odyssey II to have use of a keyboard. But mostly I would just play it with out a keyboard using the sliders. Or plugging in a guitar to it. It definitely will require work to get her in “brand new” condition. But as it stands this synth is in GREAT shape! I’m also including a binder full of patches! I’m selling her as is, buyer to pay s/h to be determined based on weight etc. (I won’t rip you off. See my feedback. I’m a good seller!)” Click here to visit listing on eBay

“Up for sale is one ARP 3604P keyboard in 100% working condition and great cosmetic condition. All keys are even; it was recently calibrated, so all 4 octaves are bang on 1v/oct exactly. This unit was VERY well kept, and bought from the original owner; the bushings are in fine shape, and the manual does not play “clanky” like some pratt read manuals get when the bushings dry out. I had a custom packaging job done to ensure it will not be damaged in shipping. ” Click here to visit listing on eBay

“ARP 2600P and 3604P Keyboard.

2600 serial # 26761
3604 serial # 36720

This is a great opportunity to obtain a classic synth that needs minor repairs at a very reasonable price.

I’m selling my ARP 2600 to fuel my 5U modular addiction. I’ve owned this ARP for 10 years. I’m an amateur musician and this instrument was used in my smoke-free home studio.

It has seen little use in the past five years. The tolex is not in great condition as can be seen from the photographs. There is no damage to the underlying wood case. When I plugged everything in to test it, I found the ENVELOPE SECTION IS NOT WORKING. EVERYTHING ELSE FUNCTIONS AS IT SHOULD. Some of the sliders are scratchy as one would expect with an instrument this age. There are three missing slider caps (left speaker, one inverter and the lag slider in the voltage processor section). Both speakers work. All keys on the keyboard work. The lowest G key is slightly raised but functional.” Click here to visit listing on eBay

“grey arp 2600 V2.0 from 1971
its the way more rare version with the original logo
and the more amazing oscillators. well 2 of them.

ocs 1 & osc 2 are 4027 (very rare)
osc 3 is the 4027-1, which was used later in the g-clef models.
it has the 4013 moog ladder filter, which is completely identical to the 4012
besides some different attachement points of how to implement it in the arp solo of that time.
http://www.till.com/arptech/modmain.htm

it sounds truly AMAZING, (imo better then the 72-75 g-clef arp 2600 of a friend i heard a while ago) and works flawlessly.
it has the 3604-p keyboard, which has been bushed and completely restored by its previous american owner a couple of years ago. plays exceptionally well (since its known to be a troublesome keyboard, but mine works great)

its in very good state for its age, but has some wear on the outside tolex and of course some scratches etc here and there. nothing major imo. see pictures.” Click here to visit listing on eBay

“After much soul searching and watching my baby sit unused for SO long now, it’s time to let someone else put her to good use…Up for sale is my ARP 2600, (ARP 2600P v3.0 to be specific). Circa 1973, it has the larger reverb tank along with the monophonic keyboard. When I picked her up 20 years ago, she had been sitting silent for years after apparently showing her stuff on stage throughout the ’70’s (note the custom 6’+ cable and neck strap buttons on the keyboard – someone wanted to be mobile while performing!). As a result the tolex is worn around the edges (see pics), no major tears just standard wear & tear from a beloved instrument. The cases have tape and stenciled numbers which for me just adds to its bad@ss-ness ’cause you KNOW she’s seen her share of ’70’s fun! All the graphics are good to near perfect, I don’t believe ANYTHING has rubbed off. All the sliders work and I think I’m missing only one or two caps (an easy replacement that I never bothered to get around to!).

NOW FOR THE FUN! She worked great from the get go, but I wanted her to SPARKLE so 10 or so years ago I shipped her off to Phil Cirocco at CMS (If you don’t know about Phil check him out! If he was good enough to repair Alan Pearlman he was good enough for me!) for a FULL audio path upgrade along with a power supply rebuild. In addition he made some repairs to unDO any “creative” repairs made in the past. The result is a smooth as silk, extra headroom sound that is PURE 2600. I will ship the keyboard and console separately, each “wrapped to invisibility” with heavy bubble-wrap before being securely boxed and shipped INSURED ONLY via UPS. Shipping charges are at $200 but it may be more or less depending (I’ll get an exact quote). Bidders outside the US contact me BEFORE bidding (along with 0 history ebayers!).

In fairly good condition considering it’s age (rusted corner and handle metalwork) and one key has an unfortunate cigarette burn (see pic)

The keyboard outputs all work fine, but is in need of some TLC – the 3 keyboard busses (CV, Gate and Trigger) need cleaning, and the keyboard springs could also do with realigning and cleaning.

Sadly the cover is missing but a simple plywood cover is supplied (see pic)

“For sale is this vintage 1972 ARP 2600 series “2600P” analog synthesizer and matching “3604” keyboard. This particular set, serial numbers 26189 and 36186, is in very good all original condition and includes the original case lids, the original gray power cable, a non-original keyboard 6-pin cable, and non-original patch cables. The ARP 2600 is considered the absolute benchmark in compact analog semi-modular synthesis. Extremely versatile, and capable of producing a seemingly indefinite amount of both classic and modern synth sounds, the 2600 has become the standard by which other synths are measured. This is an incredibly rare example in that it is from the very highly-regarded early production run with the desirable superior 4027 filters, famous for being one of the best sounding versions. I have owned many ARP 2600s, but this is the best sounding one, the difference between it and others is actually surprisingly significant, so do not miss out on this No Reserve auction with Global shipping, because these do not come along often, and when they do, have been selling for upward of $11,000.00! This is a No Reserve auction which means the highest bidder will win… regardless of price!” Click here to visit listing on eBay

“or sale is an original vintage ARP analog modular 2600 P (V2) synthesizer with 3604P keyboard in complete working condition.

The Main Unit and keyboard are working and in overall very clean condition. All of the original sliders and knobs are present and work fine. The tolex has been repaired on the front cover of the main unit. The tolex and case on the keyboard were replaced a few years ago with a sturdy maple enclosure (see photos), though some of the remaining keyboard tolex is ratty, but generally out of site. The new, sturdy hardwood case is much more attractive than the original keyboard case and will last for a long time. Otherwise, there is the usual cosmetic wear expected with an instrument of this age.

Watch a YouTube video of this Arp “in action!”

Here’s what you get:

Main Unit serial # 26034, Model number 2600P V.2.0 (made between 1971 & 1972) with Moog-type filter
Keyboard serial # 361358, Model number 3604 P
This ARP comes with the synthesizer cover (no keyboard cover), power cable and keyboard cable, and also some great extras:

– An original owner’s manual (a collector’s item unto itself) in great condition

– An original service manual, in a binder

– An original 1974 paperback copy of “Learning Music with Synthesizers” by Alan R. Pearlman, the guy who invented the ARP. In it, he describes how to make music with an ARP Odyssey, much of which is transferable to the 2600.

– Over a dozen patch cords of varying lengths.

– A Gator GK case for the keyboard. This is one of Gator’s most rugged cases and features built-in wheels with tow handle and skid bars. The case is worth $150.

There have been no modifications to this synth, but several components have been replaced, repaired and/or upgraded (see below).

This ARP is 100% functioning and looks & sounds great. Per Phil Cirocco of CMS, the 2600P V.2.0 (this model) was the last ARP to have a good audio path, and that most ARPs afterwards, including the orange faceplate 2600s, have a much hissier sound.

The restored keyboard has great action, and its hardwood case is a thing of beauty.

“Up for sale is a vintage, all original, un-modified, very gently used, 1973-74 ARP 2600 series “2600P V3.0” analog synthesizer and “3604P” keyboard. This is an incredible, all original model for a musician seeking to purchase a vintage ARP 2600P. There are no missing pieces, and there have been no alterations. It has been recently cleaned, serviced, and calibrated to factory specifications.

This version of the ARP 2600P contains the infamous and sought after ARP 4012 filter (see photo).

The keyboard had new factory specification rubber bushings installed for each key, restoring the action of the keyboard to “like new” performance standards. The keys work perfectly with aligned, even-tempered action. All of the keys are intact, un-chipped, with no cracks. A few of the white keys at the low end of the keyboard, have some staining (see photo).

The face of the console and keyboard have a few, very minor, scratches. The black tolex exterior of both road cases that house the console and keyboard, are scratched and torn from normal wear and tear. Both travel cases are original and structurally sound with the original handles and clasps (tarnished), in excellent working condition. This console and keyboard have matching serial numbers: Console: Ser# 261523 and Keyboard: Ser#: 361523. The set includes the ARP 2600 console and 3604P keyboard in their original travel cases, the original gray power cable and gray console to keyboard cable, 4 patch cables and, the original ARP 2600 sound effects patch book. ” Click here to visit listing on eBay

All components are original except for 2 op amps. One for VCO-1 square wave out and the other for the Mixer amp. Additionally, the left speaker has been replaced. All have been tested and perform up to or better than original specifications.

The case of the synth has a few scratches on it and there is a small nick on the panel near the reverb sliders and on the keyboard panel upper right but overall with the restoration it looks really great. All knobs, slider caps and adjustment covers are present except one cover for the negative null which in no way affects operation.

The cable that connects the keyboard is from Phil Cirocco at C.M.S.
There are a lot of patch cables as well as bag of wires and jacks.

The unit has not been re-tolexed as you can see from the pictures. This particular synth has the Moog 4012 filter and it sounds amazing.

I value my perfect feedback and accept returns, so bid with confidence. I have sold several expensive synths on eBay. I am selling off my entire studio and moving to Sweden, so please check my other items. I have done my best to represent the condition of this synth in the photographs so please zoom in, check them carefully, and let me know if you have any questions.
