Neon Knights
The fastest thing Sabbath ever opened an album with, and the first Iommi tone that does not run a treble booster. John 'Dawk' Stillwell rebuilt six Marshall 1959 Super Leads with an extra gain stage for the Heaven and Hell sessions -- 'he'd done away with the treble booster I had forever,' as Iommi put it -- so the gain finally lives inside the amp instead of in a box in front of it. At this tempo that matters: the boost is gone and the note separation comes back.
Heaven and Hell
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 6 blocks replaced with a stand-in model
Which ones
Replaced with a stand-in: Gate, Studio Comp, Plexi 100 Jump, 4x12 Greenback, Chorus, 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 2 blocks missing from the file; 5 blocks replaced with a stand-in model
Which ones
Not in the file: Delay, Reverb. The recipe calls for these blocks, but we have no verified model ID for them on this platform, so the preset is written without them. Add them by hand using the settings above.
Replaced with a stand-in: Crunch, Booster, 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.
