Mine was last night. To set the scene...
My gear - Bass -> pedals -> DHA VT-1 Bass-EQ-Drive -> [DI to FOH] -> amp
During set up there were a few squeals and pops coming through my amp which seemed to be cured by switching on the VT-1. Weird?
Anyway - midway through the first set my amp dies. No biggy you may think - the DI is from the preamp, just get some bass back through the monitor. Simples! Only... there is no signal to the desk.
Cue a hasty switch to a passive DI and some swearing.
Got the DI situation sorted in the interval, then half way through the second set my Power Plant gives up!
Back into the DI - after a bout of very loud, very pissed off swearing
Sound guy did a sterling job, but all that gear packing up in one sitting? REALLY?!! Best get out the ol' multimeter...
Anyone with a similar nightmare?
