I totally agree with PTLEFTYBASS about the fender rumble 200watt 115 combo,best bang for the buck imo & can add an ext cab if needed. btw-way below your budget @ GC. for the size of venue you wrote about it's perfect,but be aware that lots of reggae gigs maybe outside/outdoors,so an ext cab may come in handy and still be obtainable in your wallet or close to it.
