hi. i played a gig with my ashdown mag rig on thursday and right at the end it just cut out. the vu meter was still on, so i thought my sansamp bddi's battery had died so i took it out and just went bass straight to amp. however, the vu meter needle was going very high when i played but no sound at all came out. at practice yesterday when i turned my amp on it made a buzzing sound then a loud crackling sound so i turned it off. the vu meter still came on though. i unplugged my extension cabinet and just tried the combo and no buzzing was heard, but when i plugged in my bass no sound came out again and the vu needle didnt move. any one any thoughts on what could have happened?
