Why these settings

The Harley Benton HB-40's Overdrive channel is pushed to gain 7 to capture Tony Iommi's cranked Laney power-stage breakup without external pedals. Treble is dialed to 6 and mids to 7 to replicate the bite of a modified treble booster hitting British power tubes, while bass is kept thick at 8 for the iconic doom sludge. Presence is null as the HB-40 lacks a presence control.

PRO TIPFor the iconic riff, slowly sweep your picking hand closer to the bridge to accentuate upper-harmonic overtones, and if you pick up a wah pedal, rock the treadle in slow, hypnotic half-measure sweeps rather than rhythmic funk-style tapping.
