I was playing at practice last night, drummer unplugs my EH Microsynth from the power strip, then plugs it back in. There was a "pop!" from the amp, and then....nothing. When I shut it down and turn it back on, the first blue light just flashes and flashes, and clicking the stand-by switch causes no discernible change. Did my drummer fry my amp? Should drummers never be allowed around anything that they can't justifiably hit with a stick? What would be the thing that went wrong here, and is it going to cost a fortune to fix? As luck would have it, was due to start playing w/ a new band today, and....not gonna happen.
