The Mob Rules
There are two recordings of this song and they do not sound the same. The first was cut at John Lennon's old house at Tittenhurst Park for the Heavy Metal film soundtrack; the album version was re-recorded months later at the Record Plant in Los Angeles with Martin Birch. Both run the boosterless rig Iommi had been on since 1979 -- a Marshall 1959 Super Lead rebuilt by John 'Dawk' Stillwell with an extra gain stage -- but the LA version is tighter, drier and considerably more aggressive.

What we checked
Computed by a program, on this recipe, every time this page is built. How this works
Preset files — 1 of 3 complete
- Helix builds complete — every block in the recipe is in the file
- Quad Cortex 5 blocks replaced with a stand-in model
Which ones
Replaced with a stand-in: Gate, Studio Comp, Plexi 100 Jump, 4x12 Greenback, Room Reverb. These load cleanly but are not the model named above — the file will sound wrong here until we map them. Set these blocks by hand.
- Katana 1 block missing from the file; 4 blocks replaced with a stand-in model
Which ones
Not in the file: Reverb. The recipe calls for this block, but we have no verified model ID for it on this platform, so the preset is written without it. Add it by hand using the settings above.
Replaced with a stand-in: Lead, FX, Delay, Reverb. These load cleanly but are not the model named above — the file will sound wrong here until we map them. Set these blocks by hand.
What we didn't check
- Nobody played this through a real amp. There is no human listening test behind any number on this page.
- The settings are reasoned from the sources below, not measured off the record.
- No audio has been rendered for this recipe yet, so you cannot hear it before you load it.
- 3 platforms on this page (TONEX, Kemper, Fractal) get a model pointer, not a preset file — nothing was built or checked for them.
