after years of struggling to get adequate overdrive from my non-mv marshall jmp without blowing singers of the stage, i finally figured it out. and it didn't cost a thing. at a show on saturday night, i asked the sound guy if i could just face the cabinet into a corner at the back of the stage. he said "good idea" and put the mic back there. i could finally crank it loud enough to hit the tubes, but no one was getting the full-frontal directional assault. i was using a sealed 2x12 cabinet, so if it were facing out, the sound would have been just hitting my knees anyhow. is this common practice? if so, i wish someone would have told me five years ago. anyone else do anything similar?
