ARP 2600

2600 tech specs

The 2600 was a semi-modular synthesiser made — and constantly revised — by ARP throughout the 1970s.

It was released shortly after EMS's VCS3, making it one of the first semi-modular synthesisers ever made. It's also one of the first synthesisers to sport sliders instead of knobs.[1]

It's quite possibly the first semi-modular synth to have its sockets internally normalled to a sensible patch, so that musicians favouring immediacy can just turn it on and start jamming out, while sound designers favouring versatility can still override these internal connections to create weird and wonderful oddities — the best of both worlds.

After an early blue version lasting less than a hundred units in the early 1970s, the 2600 was re-released in grey. In the late 1970s, as part of ARP's overall rehauled design aesthetic, it was redesigned in black and red. This colour sceheme lasted as long as the company, until the early 1980s. The grey version's therefore the most common. Under the hood, however, the black version received an update, and the grey one underwent several changes, chiefly replacing the filter.

The 2600 originally featured a clone of Moog's stellar lowpass filter until Moog noticed,[4] spurring them to replace it shortly before the changeover to the black version with red trimmings.


I still use the 2600 on occasions because there's nothing to replace it, and because I've developed a dialogue with it over the years. I tie it and the sequencers into the rest of the system with a click out from the DMX.

— Steve Roach, 1987[5]

It's tops for bass. It's got a certain sound to it that I just used to hear on things like Stevie Wonder albums. It's all hardwired, but you can patch it up and bypass it. It's much like the Minimoog, but with sliders instead of knobs, stereo speakers, and a built-in spring reverb that clatters every time you walk past it. It's got three oscillators, so it's pretty chunky.

— Graham Massey, 808 State, 1992[6]

This really is a fantastic synth: brilliant sounding, heavy-duty, really sharp envelope. There are actually two kinds of envelope on it, ADSR and AR. Nice spring reverb, two speakers. Who could ask for more?

— Vince Clarke, Erasure, 1993[7]
