I'm in an acoustic band (normal electric bass) doing a small gig where we're not meant to be filling the whole bar with sound. As such bands usually plug into the PA or bring their own kit. Unfortunately I don't have a big amp so am looking at plugging my Line6 combo into the xlr. The other band members reckon this will allow for a much better sound all-around and my combo would become my monitor. I'm a bit nervous about setting up like this but agree that renting a 4x4 and amp would dominate the sound near to the band and give nothing toward the back of the bar. Has anyone setup like this before? Any suggestions?
