The recording
The track was recorded at The Mansion in Los Angeles in 2004 under producer Rick Rubin. Jim Root and Mick Thomson’s rhythm guitars were double‑tracked and layered, creating a massive, aggressive wall of sound. The guitars were captured dry and then processed through a Mesa Boogie Dual Rectifier and an Ibanez TS9 Tube Screamer, with additional EQ and compression to tighten the attack, placing the guitars front‑and‑center in the mix.

Practical playing approach
Recreation guidance, not a claim about undocumented studio control positions.
- 1.Set the pickup selector to bridge position and engage the high‑output humbucker.
- 2.Drive the Ibanez TS9 Tube Screamer into saturation before the amp.
- 3.Set the Mesa Boogie Dual Rectifier’s gain high with scooped mids and tight bass for a heavy chug.
- 4.Use aggressive alternate picking with palm‑muted low strings and add a touch of reverb for depth.
