Slightly modernized version of a the old wierdo Roland AG-5 Funny Cat. Original had discrete op amps and a transistor emitter follower which for this layout has been changed to regular op amps.
It is also modified for true bypass.

Verified with the following correction to stripboard: reverse polarity for d2; without that there is no squealing effect.
ReplyDeleteTried 2sk30a and j201, but finally preferred the bf245a which gives a more usable pitch/ squeal and the distortion sounds richer.
Thanks! Updated and tagged.
