Right as the clock struck midnight, I heard a pop out of my cab and then all the LEDs on my SM9.2 went dark and started flashing a sequence. Nothing was plugged in and the amp was on mute. Was working fine just a few minutes before. I'll call my dealer tomorrow and start getting warranty stuff figured out, but I'm a little bummed. I gig pretty regularly and this is my main amp. I'm fine with my Acoustic Image backup amp, but still... The only thing I can think of was that last week I was rehearsing in a new-to-me space and the power was pretty bad in the floor socket I was plugged into. The amp popped a few times before I got it to a cleaner power source. Maybe it was damaging enough then that tonight it just gave up and went into protection mode. Tonight's pop was the same kinda sound - sharp and loud - but my power at home is fine. My Monster Power strip (which the amp *isn't* plugged into) didn't notice any anomalies, and the voltage is right at 123VAC.
