Sequential Circuits Pro One Synthesizer Synth

This is an original Pro One with a 37-note J-wire style keyboard. I have installed new Pratt & Read rubber bushings for the keys, and have kept this synth stored in my closet for the past 12 years. I also recapped the power supply and reflowed all the solder joints when I acquired the keyboard for my personal home studio.  The previous owner drilled two holes in the case (see photos) for reasons I never understood. It never really bothered me, but could be a perfect location for MIDI in/out should you choose to go down that path.

I have tested all keys, knobs, switches and both pitch wheels with my headphones, and all work great! Also included are the original operating and technical manuals. Both have been written in (original owner again), but are otherwise in fine shape.

To answer a few questions upfront - (1)  Yes, that is the correct serial number; (2) Yes, the J-Wire keyboard is original; and (3) not everything you read on the internet is completely true. This Pro One could very well be one of the very last J-Wired keyboards produced - possibly the best out of the entire production run? You be the judge of that.

I am relisting this synth due to a non-paying bidder. Please do not waste my time and yours if you do not have the funds to pay for this synth!


Please look at the photos and ask all questions you have. Shipping is via FedEx Ground - packaged this Pro-One is  30" x 24" x 12" and weights 25 lbs. It will be shipped in a new, double-walled cardboard box. I will ship internationally.  Please note I do not set the freight costs - eBay does based on the above dimensions.
