THIS IS THE ONE!
My wife and I do a lot of outdoor gigs covering large areas and without power. A couple of years ago when I explained our needs to Sweetwater's GREATEST representative, Geoff Allen, he recommended this amp. We purchased it, and we have never had the slightest reason to regret the decision. It's so good, so portable, so loud, so clear, and so dependable, we always find other performers AND the masters of ceremonies asking us to substitute it for whatever they brought. We've combined it with an excellent microphone and my exquisite Composite Acoustics Cargo Travel-size guitar, both of which I also purchased from Sweetwater, for our own music; and we use it to play all sorts of digitally recorded music for my wife and her belly dancers, the fire performers, and others at our events. The battery pack is easy to work with, and it is SUPER DEPENDABLE. You take it on stage, plug in whatever microphone plus the instrument or electronic device you're using, and perform. Easy! Yeah, we love it. We like it better every time we use it.
