This is a very special, obviously rare synthesizer. It is in excellent condition. I purchased this from Sonic Boom of Spacemen3 and Spectrum(I can provide proof/put you in touch to confirm this if you'd like). I had it serviced by a very well known EMS tech in August 2008. There is no serial number on this unit but Sonic was told that it was #1 when he bought it back in the mid 90's. Cosmetically, the biggest issue is that the plastic frames around some of the switches are gone. I never spent any time looking for these but I imagine that they are difficult/impossible to find. There are small tears in the tolex covering. All switches and pots are working 100%. The only thing worth mentioning is that during the shipment of this from the UK to SanFrancisco, the C key got pushed in about 2 millimeters and will rub against the C# key when pushed all of the way down. I'm sure that it would be a simple fix for anyone, but it never bothered me."
