"Moog #35 analog synthesizer circa 1976. To my knowledge, there has never been another like this on Ebay. The #35 is probably more rare than the #55 as there are no pictures of it anywhere on the web. A #55 was currently for sale for $35,000. Lights alone are so cool that coming into a room and seeing it is enough to make your heart skip.
Auction includes a Moog 951 keyboard controller complete with original military surplus type connections as well as a #55 sales brochure. Behind the rear panel it reads Model 350-000 S#9042, Oct. 26 1976. Outer walnut casing is in great shape with only minor scratches and dings. It would probably look even better with a little oil or furniture polish but I haven’t done anything to the original finish. I have decided that the wood is poplar wood stained walnut. The inside is museum grade wiring; beautiful and untouched by human hands since factory, as far as I can tell. The synthesizer has a power cord but I don’t know if it’s original. One key is missing but easily fixed at a reputable keyboard shop. Keys are a little sticky as it needs to be played. No patch cables are included in this auction...
