I'm desperately trying to modify my amp settings in order to get that Metallica style sound that you hear in songs like Master of Puppets. I just can't seem to get it though...Any help? I have a Marshall MG15DFX (http://www.marshallamps.com/images/products/mg/mg15dfx.html) and a Schecter Omen 6 guitar (http://www.pulseonline.com/schecter10.htm). I know that this is probably not the best equipment to have to try to get the Metallica sound, but please help me out here. Thanks.
