Circuit Overview:
A cheap digital sampling synth with simple envelopes, and some ROM samples.
Service Tips:
They all have a bug. If you leave them plugged in they do strange things and default on by themself but..not really. Just the kind of 'on' where they make annoying sound in the mix that you don't know where it's coming from. They auto-turn off also and lose any data after 5 minutes. But for a buck fifty what do I expect? :-) Can't believe what these sell for again. 80 bucks sometimes!?
Parts:
Easy to come by on ebay. Ok now they sell for too much. Should have gotten a spare when they were 1.50 at the thrift store.
