Ok, so this listing is admittedly a bit of a flex... But we are so excited to have available, all at once, the three classic Yamaha CS analog poly synths - the CS50, the CS60, and the holy grail CS80. All three have been fully refurbished and calibrated by Syntaur's tech dream team. This is your chance to own the Yamaha CS Trifecta!

Each synth includes the lid, and the hard-to-find expression pedal. The CS50 and CS80 include the legs; the CS60 does not include legs. All three synths have had their power supplies rebuilt, have had nearly every circuit board checked out and brought up to spec, and have been fully calibrated - an intensive process that tunes the voice boards, filters, VCA response, filter and VCA envelopes, aftertouch and velocity sensitivity, chorus, ring mod, etc. All of the CMOS logic chips have been replaced. The proprietary Yamaha VCO chips have been matched in each synth for similar drift characteristics, allowing for the most stable tuning. The ribbon controllers on the CS60 and CS80 have been completely rebuilt with new contact springs. In other words, these classic synths have been brought to factory standards, and future-proofed to the fullest extent possible.

These synths are for sale individually, and when one sells, the Trifecta will no longer be available. But if you buy all three, the price will include free delivery, in person, to any point in the continental US. For buyers outside of the US, you will need to make crating and cartage arrangements.

The CS80, CS60, and CS50 are all listed individually on Reverb also: https://reverb.com/shop/syntaur

The CS60 is a Japanese model, and will require a step-down transformer when used in North America.
