Vintage ARP Omni 1 Keyboard Synthesizer Refurbished with LED Sliders

Description

This synthesizer has just been fully serviced by Synthchaser, the United States’ top ARP specialist – recapped, new key bushings, new LED sliders, new reliable pushbutton switches, 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.

Here’s a video showing that this keyboard is working great!

Has a some scratches on the case, which is common to these synths, see photos.  However, the keyboard sounds great and has been completely overhauled inside with hundreds of dollars of new parts and many of hours of labor, including:

• Synthchaser Precision LED slider upgrade.  All 15 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.  The LED colors match the color scheme of the panel graphics.
• 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.  I just started using these caps, and they look and feel awesome!
• Synthchaser replacement pushbutton switches – All 10 of the original pushbutton switches (which are notorious for having the mechanical latches break) have been replaced with retrofits.  The original switch caps are still installed so they look the same from the outside.
• 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 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, key contacts adjusted, and keys ultrasonically cleaned
• Oscilloscope calibration – Fully calibrated to factory spec using oscilloscope and frequency counter.
• Wood side panels refinished
• New power cord and new rubber feet

Prospective buyers are welcome to come try it out before purchasing.  Local pickup is welcome and encouraged.  If you pick this up and pay cash, I will include a free softshell keyboard case.  If being shipped, the instrument will be professionally packed by the UPS store and insured for the full purchase price, but this is a vintage electronic item, so all sales will be as-is and final.  But visit the Synthchaser youtube channel and rest assured that a high quality detailed restoration was done to this synthesizer by the ARP Synthesizer expert!
