All of the amps used by Stevie are from Uncle Malcolm. Here are amps one through three, which include a 1971 Marshall Super Bass (top—Malcolm’s No. 1 amp), a 100-watt 1966 JTM45 (middle), and a 1976 Super Bass. Unlike Angus’ Marshalls, none of these have a master-volume mod and these amps power six Marshall 4x12 cabinets that are loaded with Celestion Vintage 30 speakers.
