Why it sounds like that

The intro is built on distortion and wah-wah effects on the bass, and Kirk Hammett called its note choice a weird chromatic thing. Its opening four-bar riff exemplifies Burton's lead-bass approach and fingerstyle technique. A Morley Power Wah Boost can be heard on the track, and a flanged bass line runs between the crashing power chords. On Metallica's first two albums, a Russian-made EHX Big Muff powered his distorted tone. The Rickenbacker 4001 he played on Kill 'Em All and Ride the Lightning had its original pickups replaced with a Gibson EB in the neck and a Seymour Duncan Stacked Jazz in the bridge, a set-up that suited his heavy effects use and fingered style.
- Play the opening four-bar riff fingerstyle, with a lead-bass attack.
- Add a wah and distortion for the intro.
