This is is a Yamaha PSS 560 Digital FM Synthesizer 80's for parts/repair. It powers on and makes sound. The only problem is that a few of the secrets require to be pressed really hard for them to make a sound. All secrets appear to sound, just some requirement pushing more challenging than others.

　　Cosmetically it looks excellent. Has light scratches from basic use. Appears like some kid may have colored the back of it with a crayon at one point.

　　There is no power supply with this. I made use of one I had simply to test.

　　e-mail or text just (no phone calls. i will not address nor call you back).
