so ive seen a few threads about 6505's and im posting this question on a few forums.... It seems my 6505 has just stopped working suddenly... The power tubes light up when i strum my guitar, but there is absolutley no sound coming out of the cab... Ive checked all conections to amp from guitar, amp to cab, and ive even disconnected my effects loop stuff and foot switch.... Could it maybe be a fuse? PLEASE HELP lmao....
