Bk butler bluetube pedal repair help!!
I am currently working on a bluetube pedal for someone, the problem was that the eq section was not working but the pedal was functioning otherwise. I replaced a potentiometer and now there is a massive buzz and pedal on sends through a faint distorted signal when you hit the strings, the same when the pedal is off also. I have tested the pot and it's good, would like some input before I try more experimenting given it's not my pedal.
