Why these settings

The VT40X is a modeling amp—select the NU METAL or US HI-GAIN model to approximate the 5150/Rockerverb saturation. Unlike the original tube amps, the VT40X has less natural low-end thump, so bass stays conservative at 5 to avoid flub; mids dropped to 3 for the signature scoop. Your Jim Root Tele with EMG 81 is identical to the original—no pickup compensation needed. Roll tone to 8 to tame the EMG's ice-pick highs on palm mutes.

PRO TIPTune to Drop B with heavy strings (.012-.054 minimum) and pick directly over the bridge pickup pole pieces with a stiff 1.0mm+ pick angled slightly—this attack angle is critical for Mick and Jim's percussive chunk on the main riff.
