Okay, so my band got asked to play an acoustic set ( acoustic guitar, bass, vocals, unsure if there's a PA) in an "organic furniture store" (not sure what to expect lol) and I'm not sure which amp will cut it, and I'd rather not bring total overkill. My Hartke 3500 into a 2x10 seems a little overkill, but my next smallest amp is the tiny 1x10 Fender Frontman combo I use for practice in my dorm. Part of me is afraid that's too small. I've never seen this "venue", and I'm not really sure how big the room or crowd will be. What would you do in this situation?
