I'm posting this here, b/c I don't want to infringe on everybody's guitar-talk. ...but it is an amp-related question. Amp-related, b/c I'm starting a side-project and we're trying to help our vocalist get a cheap PA that can be heard over my 100 watt full stack, a full drum-kit and a bass rig. We are placing a great deal of emphasis on volume and power for this project... however, we don't have much money to work with. Budget = <$500. Any suggestions? Thanks everybody!
