TBH, I could have done a better job - I'd rate it as 'competent' - and left myself a bit more headroom when we rigged last night. So I'm kicking myself a bit and trying to work out how to deal with a few things. I'm tempted just to go out and buy a couple of guitar amp stands for when I find bands with amps on the floor - the guitarist just doesn't hear the levels right so I was fighting a little to balance things.
I also feel really bad about my own keyboard patch levels varying after having another bugger do it to me - although in fairness, I've almost sorted mine. Must buy my FOH a nice pressie...
