Crazy train amp settings — Marshall DSL40CR
The Ozzy Osbourne guitar tone for “Crazy train”, dialed in for a Marshall DSL40CR with a Epiphone Les Paul Classic. Studio version, Blizzard of Ozz (1980)
1975-76 Marshall JMP 1959 Super Lead MKII 100W (channels jumpered, slight overdrive), 1974 Gibson Les Paul Custom with T-Top humbuckers, MXR Distortion+ (Output: 10, Distortion: 4), MXR Ten Band Graphic EQ (+10dB boost at 500Hz)
| Knob | Setting (0–10) |
|---|---|
| Gain | 3 |
| Bass | 2 |
| Mid | 6 |
| Treble | 7 |
| Presence | 5 |
| Reverb | 0 |
| Master | 6 |
01MXR Distortion+
This is your primary gain source — Rhoads ran the amp relatively clean and pushed it with the Distortion+
02MXR 10 Band EQ
The 500Hz peak is the secret weapon — this mid hump is what makes the tone cut through and sing
03Emperor Chorus
OFF for this tone — producer Max Norman added subtle chorus/delay during mixing, not from Rhoads' rig
Your DSL40CR's Classic Gain channel replicates the JMP preamp topology. I set amp gain LOW (3) because Rhoads ran his Marshall barely breaking up — the Distortion+ does the heavy lifting. The Epiphone's Alnico Classic humbuckers are warmer than Rhoads' T-Tops, so I kept treble at 7 to preserve bite.
