Good luck on your gig tonite, I played a show on Deep Ellum in Dallas last nite and it sucked, I had ZERO monitors for the entire show after the first 30 seconds or so of the first song.
As far as your problem, it's a ground, and I say that with about 99.9999% certainty. Either something is switched somewhere, something is loose, something is crossed over, or whatever, but I'm almost POSITIVE it's a ground.
