ARP 2600 with ARP 3620 Keyboard

“Super-rare vintage ARP 2600 Semi-Modular Analogue SynthesiSer with matching serial Duo-phonic 3620 silver livery.

They have been well looked after and loved throughout their ownership. However, like with all vintage musical equipment, they are due a service. For example, the sliders and jacks need cleaning and re-greasing. But a very well made and rare piece of equipment that is well worth the money, the time and the love! ”

ARP 2600 with ARP 3604P Keyboard

“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 search for synths on eBay

ARP 2600 with ARP 3604P Keyboard

“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.” Click here to search for synths on eBay

ARP 2600 with ARP 3620 Keyboard

” Rare Arp 2601 Synthesizer. It’s time for it to be used to create music again! For many years, it was stored in a spare bedroom closet, and for years, I was going to have it restored and brought up to spec, but alas…, I ran out of time and interest… I did plug it in and turn it on… and all three oscillators generated tone, and they seemed fairly steady (no severe audible drift when tuned to A440 while on). However, I did not go through and test all of the functions and/or all the other modules.
You can see that there were some professional modifications added/done on this one (see pics). It may have been done by Phil Ciricco, the synth wizard at CMS. The quality workmanship of the switches/pots installed is evident, although I can’t say for certain:
3620 KYBD- 2 switches added on right side of controls. Function? Not sure.
VCF Potentiometer- Perhaps variable KYBD voltage control? Not sure.
ADSR- A switch installed and Sustain and Release output jacks? Not sure.
The buyer of this unit will need to invest some time and money in testing, calibration, and possibly some repairs, however the Arp 2601’s are rare and well worth the investment. All the switches, knobs are complete and the tolex has no major tears or holes. Some of the slide potentiometers are a little sticky- none are frozen, but they will need to be professionally cleaned and lubed. This unit looks excellent for being almost 40 years old- as if it lived in a recording studio most of it’s life! What you see in the pictures is what you’ll get. It is being sold as with no warranties whatsoever. I will securely pack the unit in two boxes (main unit and keyboard) and insure it for shipment to the lower 48 States of the USA only. Thank you and best wishes creating music!” Click here to search for synths on eBay

ARP 2600 with ARP 3620 Keyboard

“Stunning original condition and superb working order. Complete professional service completed in February 2018 by US Arp specialist. Checked over by our resident synth expert – it is in superb working order. The front panel, controls and keyboard are all superb and undoubtedly in exceptional original condition for a 2600 of this age. The keys of the 3620 keyboard are showing some age in terms of fine scratches and scuffs but overall this is also is excellent condition. The tolex has some wear and scuffs – mostly on the edges – but nothing serious. Overall this is an outstanding example of an exceptional instrument – the best we’ve seen.” Click here to search for synths on eBay
