Oberheim Matrix 12 keyboard with individual outs in Detroit, Michigan For Sale

Oberheim Matrix 12 keyboard with individual outs
Price: $xxxx
This Matrix is a US made version with the rare individual outputs done at the factory.
The keyboard was serviced about 2 years ago Which included cleaning and calibrating the rotary encoders and other pots as well as replacing battery. The keyboard was then stored in flight case. Everything works well and it passes all internal tests.
Cosmetically this keyboard is in pristine condition without a nick or blemish.
Sound wise this board is amazing. I own many vintage synths from an arp xxxx to a Jupiter 8 and the first time I played this board I was blown away. It has such a polished finished sound. In my opinion the fattest sounding poly synth ever built.
I am also including a very nice flight case .
