Why these settings

Per the double-gain prevention rule, the Mooer SD75 is kept on a transparent Clean channel with gain low so the Nano Metal Muff provides the saturated thrash bite. Kerry King's signature sound famously pushes midrange rather than scooping it, so the pedal's Mid knob is pushed up to recreate the Boss 10-Band EQ boost. The Mooer SD75 digital combo faceplate has no dedicated hardware presence control, so presence is nulled.

PRO TIPTune down a half-step to Eb Standard and dig in with aggressive, strict downpicking near the bridge saddle to nail the percussive attack of the opening gallop.
