band has it's own gear, knows how it's meant to sound, gives an engineer less room to cock it up
The engineers will still fuck it up in my experience, even the most basic shit at our gigs like 'KEEP BOTH GUITARS AT THE SAME AUDIBLE LEVELS' was beyond the capability of our last engineer at the Sugar Club. Couldn't hear the Rythm guitar for the whole gig! I know coz I recorded it with a minidisc and mic. We were the main act. Whats the point of soundchecking again?
I'm still angry about it
