Why these settings

Iommi ran bass at 0 and everything else maxed, but the Mustang's British model has more low-end than a Laney Supergroup—bass at 3 prevents mud. Mids pushed to 8 (vs the GT's neutral voicing) replicates the Laney's mid-forward bark. The onboard treble booster is mandatory; without it you're missing half the tone.

PRO TIPIommi attacks the strings hard with the fleshy part of his fingertips (he lost his fingertips in an accident and uses prosthetics)—dig in aggressively on downstrokes to get that percussive chunk on the riff's palm-muted sections.
