Serviced ARP Omni 2 Synthesizer with Synthchaser MIDI, LED Sliders & Road Case

via this eBay listing
"Here's a nice, restored ARP Omni 2... with MIDI!! This synthesizer has just been fully serviced by Synthchaser, the United States' top ARP specialist - recapped, new key bushings, new LED sliders, clean, fully functional, calibrated, in tune and sounding great. And best of all, this has been fitted with the Synthchaser MIDI Adapter! 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.
Excellent condition, with some marks on the right leather side panel. Includes a road case that needs new foam and to be aired out as it smells musty. See photos for condition. This synth was serviced by Synthchaser (the top ARP specialist) in February 2026. Work done included:
Synthchaser MIDI Adapter - Supports MIDI IN and THRU (only an "IN" jack has been fitted on this synthesizer). Configurable MIDI channel and starting key on your MIDI controller.
Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders (purple color--think Prince!). The difference in the way these sliders feel and perform compared to the originals is a huge improvement.
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 cleaned
Oscilloscope calibration - Fully calibrated to factory spec using oscilloscope and frequency counter."
