Metallica used a Mesa MK 2 c+ preamp into a Marshall power amp w/ 6550 for Master and Justice. Those preamps have the bass mid and treble knobs in the circuit before 3 of the gain stages. So Metallica would set the treble high, some mids, and no bass, to get the tone really chunky on palm mutes, then use the graphic eq to scoop out all the mids and pump up the bass. Most amps just have the one eq section after the gain stages, Soooo with most setups you could just get an eq pedal and put it before the amp with it set to a frown (mids pushed up), and suck the mids with the eq on the amp. Its the same thing as using a tube screamer to tighten up a high gain amp, because they have a big mid boost.
