Ollie says:
I hate being asked to turn down and I hate the patronising "it's ok we have a PA for volume"..."yes mate but your monitors on stage sound like shit and if you were a half decent sound engineer you'd know that any guitar amp sounds better when you can crank it and push the speakers...get a better fucking PA if it can't handle it"
Wish I'd actually had the balls to say this.
Thing is, though, every time I see a band who do, I always think they're a bunch of cocks.
