If you want to know how the Mesa Mark's sound listen to MOP and AJFA by MetallicA. There was some studio magic but a live Mark IIC+, III, IV, studio preamp, quad preamp... are damn near dead on. In a modern setting you can always take a listen to Lamb Of God but I'm not a fan of that tone so it doesn't appeal to me. What's the asking price? Also remember that it's not a high gain monster like some of the newer amps, it has a bit of gain that completely useable but it's very smooth and open, not over saturated and aggressive.
