Hello I'm trying to build a simple overdrive pedal using a LM368 amplifier. I came across this schematic:
and I tried to build it. I have one minor issue, I can't get the drive pot to function. It is either off or on, with nothing in between. When I look at the data sheet for the LM386, I see that the example of an amplifier with a gain of 200 uses a different way of connecting pin 1 and 8, in the datasheet they are wired with the cap in between them, in the schematic for the pedal they are both wired to pin 1 and 2 of the pot and then pin 3 of the pot is wired through the cap to ground. Can anybody please explain the differences of the two wirings? And shed some light as to why my pot is not working properly?
