Hi everyone.
I recently picked up a Casio MIDI guitar controller. A really good example of old MIDI guitars. I think it uses the Roland setup on an Ibanez body. Anyway, the previous owner had it from new. The batteries died on stage years ago and he says he plugged in an ac adapter from his pedal board and that was the last time it worked. It was left in a cupboard unused and unloved for many years. I'm thinking wrong voltage or wrong polarity when he plugged in the a/c adapter..
I've not been able to find the circuit diagram although I have done a close visual inspection of the board and can see no signs of anything being burnt out.
Is anyone in the group familiar with this guitar?
It works perfectly as a passive guitar of course, not much to go wrong there.
Any help much appreciated.
Best regards
Tee.
