Why these settings

The Marshall MG30FX OD-2 channel supplies the primary Bogner/Marshall high-gain structure, while presence is omitted as this model lacks the physical control. The MXR 6-band EQ pushes 800Hz and 1.6kHz to replicate Jerry Cantrell's signature aggressive vocal midrange bark without getting overly fizzy. The Boss OS-2 acts strictly as a front-end boost with low drive to tighten the Dean ML's humbucker attack for the syncopated riffing.

PRO TIPJerry Cantrell's crushing rhythm tone relies heavily on extremely heavy, consistent downpicking right near the bridge saddles, keeping the palm-mute clamped tight on the open low D string to preserve rhythmic punch.
