Hello all, help please. I built a chunk chunk and here is my issue: bypass works, when pedal is turned on it will not pass guitar signal. Here is the kicker... it will pass signal from a generator, music, anything I try except signal from the guitar. I have tried multiple guitars, cables to no avail, just get hiss. the controls all function, as far as increasing the hiss etc. I tried connecting the input to the board directly to the input jack with same results. Tried a different input jack, I am at a lost as to why it will amplify any signal except guitar signal.
