Members jr_vw2 Posted August 26, 2010 Members Share Posted August 26, 2010 I am guessing that its a ground issue. I rewired the pedal and used point to point wiring rather that the PC board that was in it thinking it was a connection issue. I am also getting some bleed through in one of the positions. I think the bleed through is probably a bad switch but could a bad switch also cause my hum issues as well? Thanks Link to comment Share on other sites More sharing options...
Members PlinytheWelder Posted August 27, 2010 Members Share Posted August 27, 2010 You might need one that isolates one of the outputs (not cheap) or try plugging both amps into the same outlet. Link to comment Share on other sites More sharing options...
Members jr_vw2 Posted August 27, 2010 Author Members Share Posted August 27, 2010 Both amps are in the same outlet. I don't have a hum unless the pedal is plugged it. And A is worse then B Link to comment Share on other sites More sharing options...
Members PlinytheWelder Posted August 27, 2010 Members Share Posted August 27, 2010 ABY pedals are like that... You have a ground loop and it's a bit of a black art to get rid of them. The better AB pedals have a little transformer to break up the ground loop. Lehle and Radial make some good ones... Link to comment Share on other sites More sharing options...
