fwiw I don't drink at all when I play (no matter what's up with my fingers). There was a strict "no alcohol" (or anything else) rule at Victor's camp and while they weren't anti booze, the party line was nothing should get in the way of the groove. And booze gets in the way. I have a gig at Hard Rock tonight - it'll be the usual glasses of water and coke. The drink, not the snorting kind...
Hopefully the sound guy will be decent. Some guys seem to think that "good bass sound" means cutting the mids and bumping the lows. Not my favorite eqing. He'll likely use a DI. My amp has a good one and I try to get the sound guy to use that and I set it post eq so at least I retain some control over my tone. Not that I'm a control freak or anything
