Hi Mark , the chip, once cleared of the bullet proof resin, had no markings . I figure it had been sanded off.
The best guess is a LM386. I built a copy of the curcuit using a 386 , had to improvise on the inductors ,but hey it worked.
There will have to be a bit of fine tuning. I intend to use this as a sustainer , not as a hand held Ebow.
Regards
Geoff
