Why these settings

The Mesa Dual Rectifier's Modern Red channel provides the core aggressive low-end compression and upper bite heard on the record. Because the Jet JS-400 uses a standard passive bridge humbucker, run the Jackhammer on OD mode with gain low and volume high to tighten the flubby low end before hitting the preamp. Scooping the mids to 3 achieves the signature mid-90s nu-metal wall of sound while keeping treble and presence high for pick attack clarity.

PRO TIPTune down to A Standard (A-D-G-C-F-A-D) or use heavy gauge strings (.011-.056 minimum); pick aggressively right over the bridge pickup to emulate Head and Munky's percussive, clacking 7-string attack.
