I have a Hartke Kickback 12 (1 12 inch speaker, 120 watts) and I have been told I could only get away with it at small gigs because of lack of volume compared to the loud guitars and drummer. I have seen amps mic'ed before but how does that work? Would that make me be able to play big gigs with that not so loud amp? and when I mic it how loud do I put the amp volume knob? please respond... thanks..
