"The Odyssey was ARP's answer to the Minimoog, a feature packed scaled down version of the legendary ARP 2600. This particular ARP Odyssey is equipped with the 4035 filter, the infamous "lawsuit filter" that "borrowed" from Bob Moog's ladder filter patent.

This ARP Odyssey has just been serviced and is functioning very well. The Synthchaser LED slider & slider cap set has been installed, and the LEDs are color coded to correspond to the original colored slider caps, which give a visual indicator of the function of each control. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. The power supply was recapped, all tantalum capacitors replaced, new key bushings, cleaned key contacts, calibrated, and the 1/4" output jack made to a high output.

There are a few flaws I feel the need to disclose: The old silkscreen was worn away and the paint was also worn through, so I've installed an overlay. The quality of the overlay isn't the greatest, and the color doesn't quite match the rest of the synth, but anything is better than the way it was! Please review photos carefully. This particular Odyssey has a fairly high noise floor. You can hear it (white noise/hiss sound) when the tone sources are turned down and the VCA is open, or if the filter isn't fully open. Also, the ADSR modulation to the VCF can "overdrive" the filter if the slider is up all the way. Please see the attached video for a demonstration of these. There are a few extra holes on the back panel (the larger ones have been plugged) from previous mods that have been reverted. Since the cosmetics of this Odyssey aren't perfect, I decided not to invest the time into fixing these last problems and instead just offer the synthesizer at a better value."
