# Yamaha CS01
“You’re bidding on an original, one owner Yamaha CS-01 mini synth from the early 80′s. All of the buttons, keys, sliders etc. are in working condition. This instrument works as well as the day that I bought it. I used it as a demo instrument as a music teacher back in the day. It’s all original, including the original box and instruction manual. There is no damage in the battery compartment. This is one of the only synths with a breath controller input. A great retro instrument!” Link
