Vintage ARP Odyssey Mk II 2813 Synthesizer – Serviced w/ LED Sliders

Description

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 Mk II ARP Odyssey is equipped with the 4075 filter, a tasty 4 pole LPF found in all late model ARP synths.

The paint on the panel is in fair condition (see photos) and there are some vintage ARP stickers on the case.  This synth comes with illuminated LED sliders color coded to correspond to the original colored slider caps, which give a visual indicator of the function of each control.  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.
• New pitch bend knob

Prospective buyers are welcome to come try it out before purchasing.
