Notes

Studio recording, 1999 (The Battle of Los Angeles). Guitar always in neck pickup position for all Drop D Rage tracks including 'Testify'. No evidence of alternate guitars or amps for this riff section. Effects chain unchanged from early RATM era.

Difficulty

The riff requires advanced coordination between hands and foot for wah sweeps, tight rhythmic precision, and control over a high-gain, effect-laden tone. The combination of effects and physical technique makes it challenging for most players.
