A Marshall-style bass amp adds the documented natural overdrive and tube compression.

Why it sounds like that

Bob Daisley played a Gibson EB3 bass through one of Randy Rhoads's 100-watt Marshalls on the track. The album sessions used the same bass through a 100-watt Marshall, with the setup miked. The Marshall adds a little natural overdrive and rich tube compression. Daisley is no fan of effects, and none is heard on Crazy Train. The verse is a two-bar pattern of staccato quarter notes that answers the drums, and the chorus pushes forward on anticipated beats.
- Play the recurring intro on root notes only.
- In the verse, play dry staccato quarter notes in bar one, then offbeats in bar two.
