Let's say you're a guitar player on stage with your band, performing in front of an audience. The curtain is up so to speak, you're on public display, you're in what all who consider themselves "professional" to any degree know as performance mode. During one of your guitar solos another member of your band stops playing, walks behind you, puts his hands on the controls of your amp, and turns your volume down . . . what would you do? Let's also assume that the entire incident is recorded on video, so there's no denying the fact that you were already deeply buried in the mix before you got turned down. Anyone ever have this kind of thing happen to them? Any ideas as to why somebody would do such a thing?
