Forty Six & 2 amp settings — Headrush FRFR 112

The TOOL guitar tone for “Forty Six & 2”, dialed in for a Headrush FRFR 112 with a PRS Mark Holcomb. Studio version, Ænima (1996)

Original rig

1979 Gibson Les Paul Custom (Seymour Duncan JB bridge) → Mesa/Boogie Dual Rectifier (Modern High Gain channel) + Diezel VH4 → 4x12 Recto cab with V30s. DOD FX40B EQ pedal for low-end boost, Boss DD-5 delay for ambient sections.

Massive scooped high-gain with tight low-end thump, aggressive upper-mid bite, and controlled fizz on top. Percussive palm mutes with sustaining chord swells.

Why these settings

Your PRS Mark Holcomb has Seymour Duncan Alpha/Omega pickups — hotter and tighter than Jones' passive JB. Drop gain from the original's 7.5 to 7; your pickups push harder. The Holcomb's voicing is more modern and scooped than a '79 Les Paul, so raise mid from 3 to 4 to restore some of that mahogany bark. Presence stays low at 3 — Rectifier models get fizzy fast on FRFR.

PRO TIPJones picks extremely close to the bridge with a stiff attack for that percussive 'chunk' on the main riff. Angle your pick 45° and dig in hard on the downstrokes — the tone is as much in the right hand as the amp settings.
