Hey, also newbe here..
I've done quite a few diy pedals so far, but drives and distortion only, this is why I'm asking for help.
A frind of mine just gave me a danelectro cool cat which has problem with the speed knop. Either min or max the pot doesn't affect the tone.
I measured some strange values on the tl072, but replacing it didn't fix the problem.
Does anyone have a clue?...or at least a schematic..
Thanx
