ARP Avatar Custom Modified Guitar Synthesizer 1982

We purchased this from a local estate. This is an ARP Avatar that has been modified. The plaque mounted on the console says "Alvin the Unique, Custom Built for George Choksy by Jim Chandler of Chattanooga--1982". The estate we purchased it from was the Choksy estate. 

We have ran signal through the synth and were able to get various sounds from it. It does need some cleaning and some care. We weren't able to fully test all functions, due to us simply not knowing exactly what to test for. But it does produce signal and the guitar did trigger various effects. 

The modules that are outlined in blue are the modifications. I've included pictures of the inside of the console to show the quality of the modifications. We did not pass signal through any of these modules, as they appear to need to be patched together like a traditional synth. 

This item includes the original owner's manual, five(5) ARP foot pedals, an AC cable, and the flight case. The hex pickup is not included. 

The flight case does have a smoky odor to it. The sliders on the synth are all functional, but most are missing the grip. One of the sliders, the HPF Cutoff Frequency, is broken off flush to the top of the console. It does, however, still slide and function. 

Please ask us any questions you may have. If you would like more photos, just let us know.
