Hoping I can find some trouble-shooting ideas since I ran out. The problem: When I step on a pedal (turn it on) it cuts my sound off. Just like stepping on a tuner cuts the sound, except it happens regardless of the pedal (I tried 4 different pedals). After testing all the cables (all good) on my board, I decided to just try one pedal at a time. All with the same result. I simplified the signal chain to bass-cable-pedal(pick one)-cable-amp. I activate the pedal, any pedal, it kills all the sound. I used different basses, amps, pedals, cables, power supplies, pedal combinations and 9v batteries. I am truly baffled. Any ideas? Or should I have my house cleansed of demons?
