System of a Down's signature dynamic shift — a clean, fast drop-C arpeggio intro that detonates into a full-distortion chorus. Same rig as the rest of Toxicity: Daron Malakian's Ibanez Iceman in drop C (C-G-C-F-A-D) through a Mesa/Boogie Rectifier blended with a Marshall Plexi-type — Mesa for the teeth, Marshall for the body — no pedals. The trick is dynamics: roll the guitar volume back and pick lightly for the clean intro, then dig in and let the amp blend bite. Recorded dry at Cello Studios under Rick Rubin, mixed by Andy Wallace.
