I'm trying to get a GREAT metal guitar sound with the equipment i've got. The problem i'm having is the sound i record is somewhat muddy and not "tight." I'm not sure if my problem is the guitar tone i have now(which sounds great in my basement where we're recording) or the mic placement. I'm using a Yamaha AW16G to record with and a SM57 on axis with the upper left cone of my Marshal cab. My equipment is: Marshall AVT 150 Head 2 4x12 Cabs Stageworks 15-band EQ Digitech Metal Master Pedal Washburn Dime 333 with Dimebucker pick-ups Can anybody give me pointers on making my sound much more tight, crisp, and professional?
