Casio CZ-101 For Sale. We paid our tech to disassemble, clean and service this unit. The cost was significant, relative to the value of this unit. When he was done with it, we noticed that one of the keys would very rarely stick very slightly for just a brief moment once released. We also noticed that the line select 1+1' light would sometimes light up when not selected, though the line select function itself works exactly as it should. We gave it back to him and it seems he may have resolved the light issue, though it may still be there, as it was only occurring intermittently. It would have cost us too much to pay him to go in and tackle the key issue mentioned, so we told him not to bother as this issue (and the LED issue) is really minor and shouldn't effect most peoples enjoyment of this unit. Most other sellers wouldn't even spot or bother to report this stuff, but we're not most other sellers.
This is one of the few truly professional synthesizers produced by Casio. Its phase distortion synthesis is capable of creating analog-like sounds but offers a lot more flexibility than most similar analogs. You can create much more complex waveshapes and the envelope generators (which shape your sound over time) have 8 stages as opposed to the 4 typically provided with an ADSR envelope. We prefer this synth for lead sounds, bells and basses as well as weird analog/digital stuff, but it's good for most types of synth sounds.
