I'm sure I could get more specific and technical answers at a forum dedicated to music and audio gear, but I thought I'd give my favorite forum a shot first.

I'm getting ready to purchase a PA system for my band and I'm wondering if anyone here has experience in this parts.  I play acoustic guitar, but the rest of my band is a typical band: electric guitar, bass, drums.  We will be playing venues such as clubs, bars, outdoor gigs, house parties. Does anyone here have any experience with certain brands or setups that have worked.  Or have any horror stories for what didn't?

I'm sure this thread will drop into obscurity in 5 minutes, as it should considering this isn't a music website, but what the hell.  

Just get rock band and brutal legend
