BOOST — run into the front of the amp with low distortion and high level to tighten the low end and push the Katana's preamp, mimicking the original TS808 boost into the hot-rodded Marshall.

Tone 4 · Level 8 · Dist 2

Why these settings

The Katana's Brown channel replicates the hot-rodded Marshall JMP saturation, with mids slightly scooped at 4 and bass set to 6 to compensate for your Stratocaster's brighter single-coil pickup. Rolling the guitar's tone knob back to 8 tames single-coil harshness while keeping the aggressive early thrash bite intact. Your DS-1 acts purely as a tight boost (Dist at 2, Level at 8) rather than the primary dirt source, keeping the chugs focused without turning muddy.

PRO TIPAnchor your palm right against the bridge saddles for maximum percussive thud on the open-A palm-muted chugs, and use strict downpicking on the main riff to capture Hetfield's signature attack.
