My Peavey Tour 450 died at practice last night. I was just messing around before we started and slapped the low E and the amp lost power. We pulled out the fuse and since we didn't have another, used tin foil just to check if the fuse had blown (couldn't tell by looking at it since it's covered in white) and the amp immediately started smoking. I recently started using a Zoom B3. After the amp blew, we tried the DI on the B3 into the PA and it was very "hissy". Could it be possible that the B3 may have given too much to the head and caused it to die? Sorry if this is a dumb question but I know nothing about electronics? Thanks!
