"The labels look mostly in good shape and only a couple of letters look dinged. There is a screw missing on the left side panel(pictured). The previous owner might've removed it because that whole looks like there was a crack that was repaired. A couple of dings and scratches on the body but overall good for its age. This is the version that has the momentary button under the mod wheel.

This synth is loud! It's a one oscillator synth but the triangle and saw can really shake a room. I didn't list as used because functionally the pulse waveform and the lowpass filter need work.

When PW/PWM is set all the way to the left it sounds fine but as you start turning the knob clockwise the pulse wave gets a little dusty sounding.

When you set the cutoff and peak on filter all the way to 10 it gets a little quiet. If cutoff is set below peak it's pretty normal sounding. Someone told me deoxit might be all those pots need but I will leave it to an expert."
