I was jamming my @$$ off yesterday at practice and I managed to pull my rack off of my speakers with my instrument cord. I guess I had the rack too far forward on the cab. The rack just flipped over on its back on to the ground! Oh $#i+, I said, and proceeded to plug everythibg back in. My QSC USA900 survived unscathed, although it was already beat up looking. My brand new Sansamp Acoustic DI, which was resting on top of the rack, didn't miss a beat. It looks a little worn in now though. Unfortunately my JBL Equalizer, which was also resting on top of the rack, was crushed like a grape. Oh well, if one thing had to go..... Cheers to the quality of QSC and Sansamp! I'm convinced.
