"The Yamaha CS80 synthesizer hardly needs introduction. If you're viewing this listing you'll already know why it's such a beautiful instrument; arguably the pinnacle of analogue polysynth design, which has never been bettered by any manufacturer in the last 40 years.
Its polyphonic aftertouch, combined with its easy user-interface makes it something musically unique to this day. Anyone buying a CS80 knows its reputation. It's a serious investment and it's also increasing in value as the years roll by. I am pricing this to reflect the considerable work and expense I've put into this particular instrument to make it one of the best CS80s around. Everyone has a price where letting something go makes sense. I love this instrument and have decided I simply wouldn't part with my CS80 for less, so am avoiding the 'Make Offer' option. Here are the reasons:
1. My one was serviced by Dusty Miller (Yamaha, Vangelis' technician) in the 90s and he put in the last, most stable VCO chips into every voice card, so it is - for a CS80 analogue polysynth - pretty stable.
2. It has extra modulation controls by the ribbon controller to add even more timbral variation to the sound if desired. (I didn't add these by the way: I bought it in 1995 with them already fitted.)
3. I have just had it serviced at great length by Andy a.k.a. Synth Prof in Suffolk UK who knows the CS80 very well, has checked it over and calibrated the key touch and also fixed the ring modulator circuit. He also replaced the ribbon controller spring with a brand new one hand-wound to minute tolerance, and generally given the instrument a full service.
4. Whilst it was at his workshop I also had it fitted with a Kenton MIDI kit which is seriously cool.
So, I've done all the TLC: it is good to go and do serious future studio work.
If you're looking for a mint CS80 in extremely good condition for its age, with its original chrome legs and case, then in all modesty this is probably one of the nicest examples that is going to be around anywhere."
