Black Dog
Black Dog's snarling, compressed riff was recorded with no guitar amp at all. At Island/Basing Street Studios in London (December 1970), Jimmy Page ran his 1959 Les Paul through a direct box into a mic channel of the Helios console and overdrove the console's mic preamp to make the distortion — then fed it through two UREI 1176 compressors in series, the first cranked as a saturation stage and the second doing the compression. Engineer Andy Johns triple-tracked it (left, right, centre). The tone that sounds like a synthesizer is a preamp pushed past its limit, not a speaker.

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 3 blocks replaced with a stand-in model
Which ones
Replaced with a stand-in: Studio Comp, Studio Comp, 4x12 Greenback. 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 3 blocks replaced with a stand-in model
Which ones
Replaced with a stand-in: Brown, Booster, 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.
