"This synthesizer has just been fully serviced by Synthchaser, the leading ARP specialist - recapped, new key bushings, sliders disassembled and refurbished, clean, fully functional, calibrated, in tune and sounding great. This keyboard is the sound of Joy Division and is all over The Cars' "Moving In Stereo", and many other late 70's/early 80's albums. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR, and a dedicated bass synthesizer section.

Good condition, scratches on the top as is common for these, see photos. This is an early model Omni 2 with the black buttons, power indicator LED, enameled ARP badge, and wood side panels. Left panel has some red sticker/tape residue on it and a chip on the bottom. See photos for condition.

Sliders refurbished - It's rare that Synthchaser will agree to restore the original sliders in these synthesizers, but when he does, he does it right! The sliders have been desoldered, disassembled, ultrasonically cleaned, lubricated, reassembled, tested and reinstalled. All original slider caps are present!
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 of the over 100 tantalum capacitors in this synth, including the power supply and filter submodule, have been replaced with electrolytics to help provide stable operation for years to come.
Synthchaser 4075 Filter Enhancement Kit Installed - The ARP Omni uses the same 4075 filter submodule found in the Odyssey, Quadra, Avatar, and Pro DGX. This has been recapped, and enhanced to provide superior frequency response.
Keyboard rebuild - New key bushings installed, buss bar & key contacts cleaned and adjusted, keybed leveled, keys ultrasonically cleaned
Oscilloscope calibration - Fully calibrated to factory spec using oscilloscope and frequency counter."
