Hi, Got a used bacchus of ebay, first the bridge pup worked like a charm, but not he neck pup, so i put some foam under the neck pickup to get it closer to the strings, now the neck pup workes perfect. but now the bridge pup wont work, i just tried switching all the pots out, but no improvement. the bridge pup do get some output but no bass, it sounds like you are playing true a 1" computer speaker. is the bridge pup DEAD? or could it be something els?
