Why these settings

The Katana's Lead amp type provides the raw British hot-rodded Marshall crunch of the early Kill 'Em All sessions. Pushing the mids to 7 and cutting the bass to 5 prevents modern low-end flub and captures the raw, cutting 1983 thrash edge. The onboard Screamer boost acts as the TS9 in front to tighten the palm mutes without adding muddy preamp gain.

PRO TIPUse strict, aggressive downpicking near the bridge saddles with the side of your picking hand clamped down hard on the low E string to get that percussive, chugging attack heard on the opening riffs.
