Why these settings

The CRUNCH amp type delivers the punchy mid-forward drive heard across the album's rhythm tracks. Dave Grohl's semi-hollow Trini Lopez has immense body, so setting middle to 8 and bass to 6 compensates for the thinner, solid basswood body of the Ibanez GRG170DX. A light touch of the onboard Booster tightens up the high-output ceramic bridge humbucker for clean, heavy articulation. Clean verse: roll guitar volume down to 6 and hit chords lighter.

PRO TIPDrop the low E string down to D and pick with aggressive downstrokes close to the bridge saddle, letting the open low D ring against the octave double-stops to create the signature churning wall of sound.
