ARP

“This vintage ARP Odyssey has just been serviced by Synthchaser in March 2025 – recapped, new key bushings, all new LED sliders, fully functional, tuned and calibrated, and sounding awesome! The Odyssey was ARP’s answer to the Minimoog, a feature packed scaled down version of the legendary ARP 2600. This late model ARP Odyssey is equipped with the 4075 filter, a tasty 4 pole LPF found in all late model ARP synths.

The Mk III Odyssey has a cool Black & Orange design that complements other ARPs of the era, and has the PPC touch pads for pitch bend and vibrato (and yes, they are working on this Odyssey!)

Here is a video functional demonstration of this synth that is for sale: (video coming later today)

The synth is in very good condition. The small panel underneath the synthesizer that provides access to the key contacts is not original. This synth comes with Orange illuminated LED sliders to complement the Orange & Black color scheme of this late model ARP. I can disable the illumination for the buyer before shipping, upon request at the time of purchase.

Work completed on the synth included:

Synthchaser Precision LED slider upgrade – All 34 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. LEDs run off their own power supply mounted inside the synth.
Illuminated slider caps – Slider caps with a translucent plastic stripe that allows the LED illumination to shine through, while giving you something substantial to grip onto. They look and feel awesome!
Power supply rebuilt – All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.
All tantalum capacitors replaced – The tantalum capacitors in ARP synths are ticking time bombs. All tantalum capacitors in this synth have been replaced with electrolytics to help provide stable operation for years to come.
4075 Filter Enhancement – This ARP Odyssey uses 4075 filter submodule found in all late model ARP synthesizers like the Quadra and the Omni. This filter was designed with a calculation error that limited the cutoff frequency. The 4075 filter submodule has been recapped, corrected to provide superior frequency response, and tested for proper operation in the Synthchaser custom test fixture
Keyboard rebuild – New key bushings installed, keys removed and ultrasonically cleaned, bus bars removed and polished, key contacts cleaned and adjusted.
Oscilloscope calibration – Calibrated & tuned using oscilloscope and frequency counter.” Click here to visit listing on eBay

“Meticulously rebuilt and better and justifiably costlier than the rest, but you came here because you want perfection, not corner cutters with excuses. We posted general info about this item on our mark 1 odyssey page, so please use our website’s search feature to find it if you’d like to know general info about this model.

This unit was painstakingly disassembled, cleaned inside and out, fully and properly serviced with future-proofing measure, by professional experts, not amateurs disguised as a shop. It’s now working perfectly and better than the rest. This work typically requires an investment of 20-30 hours of skilled vintage synth tech work plus a few hundred dollars in parts costs and is reflected in the price.

The original faders in these and their replicas are low quality, so we replaced them with much better new faders. The knobs have been replaced too with a new type that we are currently testing for reliability. This unit now works perfectly, is a real pleasure to play and should make its next owner very happy. ” Click here to visit listing on eBay

“Forget all your modern day ARP Odyssey reproductions – this is the real deal and a great example of a legendary vintage synth from the late 1970s.

I have owned this fantastic synth for many years and it was well looked after in my smoke and pet-free home studio before being stored in its flight case.

The Odyssey has CV and Gate ports which means it can be used with a step sequencer, or a MIDI sequencer if you happen to own a MIDI to CV converter.

I also comes with a very sturdy flight case, original manual, patch book and printed service manual.

The keys are even and they all play fine, however please note one of the slider caps is missing (see pics). This doesn’t affect playability at all and replacements can be easily sourced online. The sliders are nice and smooth, however one or two are slightly noisy when moved – not unexpected for a synth that’s getting on for 50 years old!

If you know your vintage synths this one needs no introduction. Famous Odyssey users include Billy Currie (Ultravox), Gary Numan, John Foxx, Herbie Hancock, Kraftwerk, Alan Wilder (Depeche Mode), Chick Corea, Roger Powell, George Duke, 808 State and countless others.” Click here to visit listing on eBay

“This is a vintage ARP Odyssey. The synthesizer powers on and makes sound (both oscillators, the filter, and the VCA all seem to be working), but needs servicing. The sliders are very dirty and cutting out of contact, the key bushings need to be replaced and the key contacts are dirty. I have recapped the power supply. Outside of the case has some rust (on the right side, and on the bottom), but is clean inside. The right leather side panel is also water damaged. Since this synthesizer is not in good condition, I decided to make this one available to someone who might want to put a little work into TLC to get a vintage ARP Odyssey at a great deal. While I have done my best to describe the functional state of the synthesizer, I’m not making any guarantees or warranties, and this is sold as-is, for parts or repair, with no returns.”
