Crazy Train by Ozzy Osbourne — Amp Settings & Guitar Tone

Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.

To recreate Randy Rhoads' iconic tone on 'Crazy Train', we'll use the Fender Mustang LT25 to emulate the Marshall Plexi sound and the Squier Classic Vibe Stratocaster for its closest approximation to a humbucker tone. The Mustang's modeling capabilities will help achieve the necessary crunch and mid-forward character, while onboard effects will cover the essential delay and optional reverb.

What Ozzy Osbourne actually used

Randy Rhoads recorded 'Crazy Train' using his 1974 Gibson Les Paul Custom through a Marshall 1959 Super Lead 100W head, powered by a Variac to achieve a creamier distortion. He employed an MXR Distortion+ pedal to further drive the amp. The recording took place at Ridge Farm Studio, with the amp cabinets miked using Shure SM57s. Rhoads often double or triple-tracked his solos to create a fuller sound.
