Thanks Bassjam, after last night I'm going to have a hard time reminding myself it can only do so much.
I played the casino with just the 112L+ and a Shuttle 6.0 head. It's an upstairs stage so it really pays to go light there. I plugged it in and played with the same settings I'd used at a rehearsal in my house the day before. That is...Mid-Scoop button in, Bass @ 1:30, Mids 12:00, Treble @ 2:30...and it was TOO MUCH. I brought Bass down to flat and turned down the Master for fear of blowing everyone off the stage. All this was before running a DI out to the board.
It looked completely silly on that huge stage, I had to put my bass (should've had a red flag on it) on a stand by the amp so people wouldn't trip over it.
