"This listing is for a YAMAHA CS60 8voice analog polyphonic synthesizer in excellent cosmetic and working condition. The CS60 is built into its own case and comes with its original lid. The enamel surface of the front panel is in excellent shape but with approximately half a dozen small (pinhead size) flakes missing. There are several minor scuffs on the Tolex of the lid, but the surface is unbroken and intact. The original legs and vinyl carrying bag (both in excellent condition) are included. The Instruction manual, service manual, foot switch pedal and foot controller(expression pedal) are all included. This is a complete Yamaha CS60 with ALL the accessories!
The Yamaha CS60 8 voice analog poly synth is the smaller version of the all-time classic CS80. And even though it is somewhat "scaled down" compared to its legendary big brother, the CS60 is nevertheless one of the most expressive and intuitive synths ever made. It's basically one channel of the 2 channel CS80, and it still includes most of the key signature features that place Yamaha's polyphonic CS-series in a class of its own. "CS" stands for"control synthesizer" - and the real-time control on offer here is indeed nothing short of stunning: the aftertouch/pressure sensitivity of the keyboard is unrivaled even today and controls either VCO (LFO amount - vibrato), VCF (LFO amount - wah wah), VCF(filter frequency) or VCA (loudness), or all of the above at the same time! 
Then there's Yamaha's famous PWM (pulse width modulation) and the fantastic ring modulator with the possibility of fading the dry and effect signal in and out, as well as processing external signals via the external input, two excellent filters, HPF and LPF in serial,both with their own resonance, a great sounding LFO with various waveforms (again including "external signal"), a brilliant portamento and glissando feature, a dual-concentric pitch bend and a massive ribbon controller for extreme pitch bending a la Vangelis' "Bladerunner" and, and, and... Sonically, too, the CS60 covers a very similar territory, with many sounds nigh-on identical to its larger cousin, while being a lot more reliable and easier to service. Last but not least, with CS80prices going through the roof, the CS60 can still be had for a fraction of the price. 8 discreet voices of vintage analog technology and all the real time control you could ask for - the YAMAHA CS60 is a very desirable and highly inspirational musical instrument with tons of character.
All keys, knobs, sliders and buttons work perfectly, move smoothly and do exactly what they're supposed to do. The same goes for the keyboard aftertouch/pressure sensitivity and all other functions. TheCS60 is perfectly in tune and remains very stable. The ribbon controller is practically pristine: no signs of wear or tear, the felt is still raised and it tracks perfectly along the entire range.
The CS60 is large and heavy, it weighs over 100 pounds, I estimate shipping to be approximately $300-$350 to anywhere in the 48 continental United States..."
