i was playing at a festival last night,the sound guys took my tsl and plugged it in so when i got to the stage all i had to do was my pedals, the amp was on when i got there, plugged in the pedals and there was no sound from the amp, turns out the guy had plugged the 16ohm cab into the 4/8 ohm output on the amp. its completely dead now. im guessing this has happened to other people on here, any thoughts on repair cost? cheers in advance for any help
