This was a pretty big mod project that Darian finished a few weeks ago on an ARP Avatar, the ARP guitar synth which is mostly just a keyboardless Odyssey with a bunch of guitar-processing junk that no one cares about. That’s just a fact. Anyway, several years ago New England Analog developed this kit to break out a lot of the CV input points and modulation sources of the synth’s architecture to 1/8″ jacks mounted on a single long PCB, and now that New England Analog has closed, a new version of the kit is available from Retroaktiv.

I just finished up an inside-out full restoration of this ARP Odyssey (Mark III). I’m replacing the slider caps, which were all missing, with bat style toggle switch caps which I soften with a heat gun until I can slide them over the shaft of the slider, and haven’t gotten the green and blue ones yet, but wanted to take this photo and do a post because today is our birthday!

It’s been almost a year since I began working on the first ARP Axxe I restored, and I was amazed by how much more smoothly this second one went, though it’s not really surprising as I have worked on over 70 synths including a half dozen other ARPs in the year since then.

The ARP Quartet is not a real ARP. It was made and sold in Italy by SIEL as the SIEL Orchestra, and then ARP bought the rights to distribute in the US and rebranded it as the Quartet. Continue reading “ARP Quartet”
The ARP Avatar is very similar to the Odyssey but instead of a keyboard it was designed to capture the notes and articulations being played on a guitar and use that to control the synthesizer. So I guess the synth is supposed to be an “avatar” of your guitar? Seems kind of sad. Continue reading “ARP Avatar”
I worked on two ARPs most of the day for the last few days, this one and an Omni 2. The filter, ADSR and VCA on the Axxe are very close to identical to those in the Omni’s “synth section.” While I was initially skeptical of the Axxe (as I am of any synth with only one oscillator), I really appreciate the fact that it lets you route the envelope generator to control PWM, which you don’t often see. Continue reading “ARP Axxe”
This one belongs to Jeff Zeigler, a great musician who also runs the studio Uniform Recording. The ARP Omni 2 is a synth where a lot can go wrong, but it has a very, very repetitive internal architecture so it’s often the same problems over and over– bad logic ICs and bad tantalum capacitors (blue circles in photo above). That doesn’t mean it’s easy to fix though!
