We were playing a popular song last night and a few YOUNG ADULT FEMALES got up on the side of the stage and were dancing. During the chorus, I waived one of them over to sing the backing vocals with me on my mic. ADULT FEMALE comes over to sing, and ends up stepping on my pedals (Boss Bass EQ and TU-3 Tuner). In doing so, she pushed up all the EQ sliders to the max. As that happened, my amp volume cut out and I could smell something burning. Had to play the rest of the gig through straight DI. I was playing my Mesa Subway head through a Genz-Benz Neo212 cab. I thought it was the head that was damaged. But today I tested the head on my other cab, and it is working perfectly. So I brought in the cab, and plugged it up. A very slight volume comes out of the tweeter, but no sound from the 12's. So what do you think it could be? Is there a fuse inside the cab? I took off the back plate, but it only displayed the input jacks and tweeter dial. In order to get inside the cab I'll have to take off the grill, and remove the speakers. Before I do that I thought I'd ask you guys for any opinions. Thank you!
