Notes & Caveats
- All amp and knob settings are from the Guitar World studio rig breakdown for 'Jambi' (2006).
- No evidence of additional pedals or effects used in the riff section except for the talk box in the solo.
- Amp settings are for the Marshall JMP Super Bass; Diezel VH4 and Rivera KR7 were also blended, but primary settings listed are for the Marshall.
- Bass set to 0 is confirmed in the source for the Marshall JMP, which is unusual but accurate for this specific tone.
- No reverb or delay is used in the riff section; the only effect in the riff is amp distortion.
- If you need settings for the Diezel or Rivera, see the Guitar World article for full details.
- Settings cross-referenced with genre and era conventions for accuracy. Adam Jones is known for a tight, articulate high-gain tone with strong mids and controlled bass, using Diezel/VHT amps and Les Pauls. The 'Jambi' riff is aggressive but not overly saturated, with a dry, in-your-face sound and no audible reverb, matching these settings.
