Notes

Studio recording, 1980, Blizzard of Ozz album. Randy Rhoads used his white 1970 Les Paul Custom for the solo, with Marshall 1959 Super Lead head and a selection of MXR pedals. Effects chain is based on studio use, not live. Tuned to standard pitch (A=440).

Difficulty

The solo requires advanced technical skill, including fast picking, legato, pinch harmonics, and expressive use of wah and flanger, making it challenging for most guitarists.
