From the post
Someone mentioned that the circuit in an earlier post would have possibly been an inspiration for this one. Not sure if i share the sentiment, since that 80's japanese design and this have basically, or in quite broad terms, just the gain pot method in common with each other. Anyway. Quite a few people seem to lke this ultra-cheap OD. And what's not to like. There's a nice, loud clipping amp followed by tuned TS-style tone control. Not that complicated, but sure does sound nice.
