Arp Omni String Synthesizer w/ LED Sliders

"Arp Omni String Synthesizer. Fully working. I recapped all of the boards except the power supply because the power supply is outputing the correct voltages. All sliders have been replaced with lighted sliders and work smoothly. Synthchaser master oscillator module installed to insure good tuning. Power cord is missing the ground pin. This was a diy project, when got this it did not work at all. After the recap and replacement of sliders it now fully works and sounds good. The next owner can play it as is but may want to consider replacing the power cord, recapping the power supply and replacing the keybushings. Cosmetically this unit is nice. There are a few scratches from normal use and storage and some keys that have marks on them but nothing major."
