i have heard that mark records his stuff directly from amp by using mics............ he is famous to use his mesa boogie tripple rectifier for that puurpose......... i also watched one of his interview where he told that he prefers to use as minumum as possible gadgets between his guitar and amp........and he said that the sound on the CD of alterbridge is mostly out of his pickups and not from a processsor...........and said dat his signature addition PRS is the best guitar in the whole world.......hheheheee...........
