Vintage synth from Eastern Germany, you can smell the communist era inside of it. Very typical earthy smell of brown PCB boards. All it needed to bring back to life was thorough cleanup of all the keyboard contacts and slider pots.  After an hour and a half with compressed air and IPA it’s back in business.

Slider pots are actually very good design, fully open accessible and designed to be cleaned, sadly I forgot to take picture.

The way this one sound is just pure filth, it’s harsh…….
