I have a Mesa/Boogie 412 cab with Black Shadows in it...
We played a gig a few nights ago and I smelled/saw some smoke and thought it was my head but my head still functions fine so I'm assuming it was my cab....
I brought it back to my practice space and noticed that the 2 speakers on the left hand side are no longer working (no sound at all)...does that mean they are blown? or...?
how is the cab wired in stereo? if you can without any difficulty, try swapping the wiring from one that works with one that doesn't find out if its the speaker that's actually broken or if the problem lies in the wiring
