Vintage ARP Omni 1 Keyboard Synthesizer Overhauled with LED Sliders

Description

This synthesizer has just been fully overhauled  by Synthchaser, the west coast’s leading ARP specialist – recapped, new bushings, new LED sliders, fully functional, calibrated, in tune and sounding great. Original wood side panels have been refinished to make it look great too.  This keyboard is the sound of Joy Division and is all over The Cars’ “Moving In Stereo”.  It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR.  Omni 1 bass is routed through the VCF, which gives the synth bass on the Omni 1 a much fatter sound than the Omni 2.  I’ve made a video to demonstrate that this keyboard is fully functional and sounds great!

Overall good condition for a 40 year old synthesizer, with some cosmetic issues as visible in the photos.   Way more time and love went into the restoration of this synth than any man should ever spend on an Omni 1.

• 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.
• Synthchaser Capacitor Kit installed – 113 polarized capacitors in the synthesizer (including but not just limited to the power supply) have been replaced to help provide stable operation for years to come.
• 25+ ICs replaced – Replaced over 25 ICs to help ensure stable operation for years to come.
• Almost all pushbutton switches were replaced with ones that latch and test OK for low contact resistance.
• 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, keybed leveled, keys removed and washed, buss bar and key contacts cleaned and adjusted
• Oscilloscope Calibration – Calibrated to factory spec under measurement by oscilloscope
• Wood side panels refinished

Prospective buyers are welcome to come try it out before purchasing. Local pickup is welcome and encouraged.  If being shipped, the instrument will be professionally packed by the UPS store and insured for the full purchase price, but connectors can come loose, damage can occur during shipment, and 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.

If you pick up and pay in cash, not only will you not have to pay shipping, but I’ll give you a free Blue ARP Anvil case (may need new foam).
