I just finished a 52 week, every thursday nite, bar/pub gig. Bass, acoustic/electric guitar, and cocktail set drummer. Gig started quiet and got quite loud at the end of the nite. I used a TC BG250 for bass, two Mackie 15 Thumps w/small Mackie mixer. All this fits in the back of a Forester along with my bass and large gig bag. Guitar player used a small Line 6 amp. Drummer used what he called an "all around mike" that hung from his neck. this rig covered the gig very well. Five light trips in and out.
