Notes

Live from Blizzard of Ozz Tour, 1980-1981. Randy Rhoads used his white Les Paul Custom for the riff section live, with the Marshall JMP 1959 Super Lead MKII as his main amp. Effects and pedalboard based on period-correct live rig, not studio. Settings are weighted averages from Guitar Chalk and Guitar World, with pedalboard details from Guitar.com and Guitar World.

Difficulty

The riff requires tight, fast palm muting, precise alternate picking, and accurate chord changes at tempo, making it challenging for most intermediate players.
