Hey guys, I am looking forward to taking the next step in my music by getting a P.A. system instead of hooking my mic into a S.S. guitar amp. I would like one decently priced but of quality. Also it has to be able to hold its own against big, mean, high-wattage amps. Any suggestions are welcome as I am a total noob on this subject. As for the mic, I will be using a Shure SM-58.
