Hi, I've had a couple friends with Carvin PA systems and they seem pretty nice. I've put a band together and I'm wondering exactly how much PA I'll need. We play surf, 60's garage rock, rockabilly and twangy stuff like Commander Cody and Duane Eddy. While we're not quiet I don't think we have the same needs as a metal band. Are these systems, based on their XP800L enough for most of what we'll run into? http://www.carvinguitars.com/group/6_channel_pa_systems While most larger venues and places that run a lot of music will have their own sound I'd like to have enough to play outdoors. Street festivals, large parties and such. Thanks in advance!
