Hey guys, i'm new to the forum. have a question about my rig. I have an SWR workingman's 300 head (600 watts @ 4 ohms) and a Hartke XL 4.5 cabinet (400 watts @ 8 ohms). I'm have to max out all volume and gain levels to compete with 2 15" guitar combo amps, drums and a singer. what do i need to do to get more volume? thanks is advance!
