Why these settings

The MG15R has a full 3-band EQ and spring reverb but lacks a presence knob. Running the Overdrive channel at gain 8 delivers the aggressive thrash bite directly from the amp. The mid control is set to 5 rather than fully scooped to retain the tight pick attack and mid-range cut characteristic of Kerry King's JCM800 setup. Reverb must stay completely off for dry, surgical thrash muting.

PRO TIPAnchor your palm tight against the bridge saddles and pick with heavy, precise downward force close to the bridge pickup to maximize high-end percussive bite on the fast tremolo picking sections.
