I'm a guitar player at home but a soundman at a local venue where a lot of amateurs play.
Inexperienced guitar players always think they gottan crank their amps (which I can understand) but usually refuse to turn their miced amps backward. I really get a kick from the guys that think they gotta crank their SS amps...
So anyway, the guitar and bass players are blasting straight from the stage using up the whole alloted 110dB. I have to keep the mains on the board way down or off to keep within the allowed limits. We hear the guitars but no singer and drums only acoustically. Sucks every time inexperienced players won't listen to the soundman.
Turn it on, turn it up, turn me loose.
