I just recieved this pedal in the mail today from ebay and it isn't really working properly. It's strange. The connection between the pedal and the amp works just fine but the connection between the bass and the pedal is messed up. When I try playing my bass (Affinity P-bass) through the pedal, there's virtually no volume unless the strings touch the exposed magnet of the p'ups and, even then, it's really quiet. I've adjusted the volume on the bass, pedal, and amp, I've checked all of the cords which work just fine, and I even changed the battery, but it still doesn't work. Any suggestions?
