Creeping Death amp settings — Marshall MG30CFX
The Metallica guitar tone for “Creeping Death”, dialed in for a Marshall MG30CFX with a Ibanez GIO GRG170DX. Studio version, Ride the Lightning (1984)
Gibson Explorer (Dirty Fingers bridge humbucker) → Marshall JCM800 2203 (Jose Arredondo mod) → Marshall 4x12 cab. Some sources cite Mesa/Boogie Mark IIC+ for lead parts, but rhythm riff is the JCM800.
| Knob | Setting (0–10) |
|---|---|
| Gain | 9 |
| Bass | 7 |
| Mid | 2 |
| Treble | 8 |
| Reverb | 0 |
| Master | 7 |
MG30CFX is voiced darker and more compressed than the original JCM800. Bass pushed to 7 (vs original 5-6) compensates for the MG's thinner low-end and restores palm-mute chunk. Mid dropped to 2 (vs original 3) maintains the scooped aggression without the MG's natural mid hump muddying fast riffs. Treble at 8 (vs original 7-7.5) adds the pick attack clarity the MG lacks. Your GRG170DX's Infinity humbuckers are hotter than the original Dirty Fingers, so gain stays at 9 instead of reducing — the MG's preamp needs that much drive to match the JCM800's natural saturation.
