UGB, when my guitar isn't plugged in, and its just pedal -> amp.. I hear nothing. So it's not the amp or my guitar, it has to be the pedal.
Ok so, I plugged my guitar and the pedal into ANOTHER amp in ANOTHER room [but close by the room my main amp and computer are in] and it did the same thing [but to a lesser extent]. When I plugged my main amp in downstairs with my guitar and pedal, there was no interference. I'm thinking maybe my computer causes the interference since I seem to recall reading that I should put my computer's amp far away from the tower (or maybe I just made that up lol).

Ok I just plugged in my old amp into the same outlet in this room and it still did the
radio thing.
