Hi everyone. Sorry I don't know much about the machine myself. It wasn't made by me. It looked like it was a DIY project someone did with self made pcb's etc. Even with a build in sequencer (the switches). Nice sounds and really analog like for example the Pearl Syncussion or Simmons SDS-3 :-)

The touch control works with a light bulb and photo cel so I could imagine the bulb would have to be replaced every now and then...
