“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
