ARP 2600 with ARP 3604 Keyboard

“Here’s your chance to own one of the first ARP 2600’s ever made–the coveted “Grey Meanie”. Before the “Tonus Logo” ARP 2600’s housed in a tolex case, ARP made 34 of these Grey Meanie synthesizers in 1971, housed in a unique trapezoidal case. This includes the matching 3604 keyboard controller and power cord. And, unlike a unit that just sold for more, this one includes the original ARP filter module, not a modern reproduction.

Both the synthesizer and keyboard controller were serviced by Synthchaser (completed in January 2025). Work done included:

All tantalum capacitors replaced (except some in submodules)
Sliders cleaned and new shafts and knobs installed (one slider replaced)
Full calibration under oscilloscope
Power supply recapped
3604 Keyboard refurbished: New key bushings, Keycaps ultrasonically cleaned, Bellcrank caps cleaned and relubricated, New keyboard cables

This synthesizer contains the following modules (all genuine ARP modules unlike in some more expensive Grey Meanie you may have seen which has modern reproduction modules)

3x 4027-1 VCO
4012 VCF
4010 VCA
4014 Ring Modulator
4015 Sample And Hold
4020 ADSR
4022 Noise

The synthesizer is in decent condition, with some dents and scratches to the case, and three holes on the main unit and five on the keyboard controller that have been plugged from old mods that have been removed. There’s also a Moog style ribbon controller mounted on the keyboard controller that has been disconnected and is not functional. Please see photos. Includes an original style oval power cord. The cables that connect the keyboard controller to the synthesizer are not original. One slider was replaced with a reproduction slider, the rest are originals.

Friendly reminder that the ARP 2600 uses Tini-D jacks, which are a slightly larger diameter than standard 3.5mm patch cords. The synthesizer was tested with Tini-D patch cords (not included). While 3.5mm patch cords will often work, their connection will be less reliable than Tini-D patch cords. These cables can be purchased from Buchla.” Click here to visit listing on eBay
