I ordered a Colorsound Tonebender off of ebay from a reputable seller, and it came in today. But, i'm playing it, you can't hear anything, i've got the volume maxed, fuzz maxed and I can hear a barely audible fuzz, but obviously somethings wrong. I've replaced the battery still the same problem. I've tried 2 different amps, 2 different basses one passive one active, still have problems. Could there be any way to fix this or do I just have to get all kinds of angry at the seller?
