I've broken my Mark IV footswitch!!!!!

[riffraff]

That's right. I was trying to figure out how to attach the footswitch to the back of my Mark IV short head & the cord to the footsitch seemed to be in the way. I tried to unscrew in & the nut came unattached inside the footswitch. So I took apart the footswitch and while I was unscrewing the cord I was also twisting wires inside the footswitch & broke at least 2 wires & lord knows what else I've done! AHHHHHRRRRGGGG!!!!!!! Needless to say when I plugged the footswitch back in nothing works. And I have a gig tonight! Luckily I have othe amps but what a drag! Guess I'm calling Mesa on Monday, huh? Or do they have authorized repair centers? Help!!!!!
