"This vintage ARP Odyssey has just been serviced in March 2025 by Synthchaser - recapped, new key bushings, all new precision sliders, 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 Odyssey features the 4023 filter, a very fat 2 pole filter.

Here is a video functional demonstration of this synth that is for sale.

The synth is in good condition with minor scratches (see photos). The power switch does not illuminate. There is a slight LFO bleed-through to the VCOs (only really noticeable when you are only listening to only one VCO, see the demo video to hear for yourself). Includes a vintage anvil case, which will need new foam. Work just completed on the synth included:

Synthchaser Precision slider upgrade - All 34 of the old original sliders have been replaced with new, smooth, high precision sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. They are fitted with original style slider caps.

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.

Keyboard rebuild - New key bushings installed, keys removed and ultrasonically cleaned, bus bars removed and polished, bellcrank caps cleaned and lubricated.

Oscilloscope calibration - Calibrated & tuned using oscilloscope and frequency counter.

1/4" output made High - ARPs of this era had an RCA jack as the high output and the 1/4" jack as the low output. As today RCA jacks are an inconvenience for most, the 1/4" jack has been made to a second high output.

New rubber feet & pitch bend knob"
