Why these settings

The Randall Diavlo provides thick modern high-gain, but the signature Master of Puppets bite requires post-gain equalization. Using the Boss GE-7 in the FX loop replicates the Mark IIC+ graphic EQ by drastically scooping 800Hz while boosting low-end punch and presence sparkle. The TS9 runs out front purely as a clean boost to tighten up the Dean ML79's humbuckers for razor-sharp palm muting. Clean interlude: switch to the clean channel, bypass both pedals.

PRO TIPAnchor your picking hand firmly against the bridge saddles and execute all rhythm riffs with strict, aggressive downpicking to achieve James Hetfield's signature percussive attack and mechanical precision.
