Why these settings

The MG30GFX lacks a presence knob, so treble is pushed to 7 to capture the aggressive bite of the blended Rectifier and Plexi. The OD-2 channel supplies modern high-gain saturation, while cutting the mids to 4 achieves the signature nu-metal low-mid scoop without turning the solid-state preamp muddy. For the clean intro, switch to the Clean channel with guitar volume at 8.

PRO TIPTune down to Drop C (C-G-C-F-A-D) and strike aggressively near the bridge saddles with a heavy pick (1.0mm+) to produce the ultra-tight, percussive chug of the intro riff.
