Studio recording, 2003-2004 for 'Duality' on Vol. 3: (The Subliminal Verses). Mick used the Maxon OD820 as a boost into the JCM800, blended with a Rivera amp. Jim Root used a similar high-gain setup but this JSON focuses on Mick's main riff tone as documented in interviews and rig rundowns.

Notes & Caveats

  • ⚠️No exact amp knob settings for 'Duality' studio session found; values estimated based on Marshall JCM800 typical metal settings and era.
  • ⚠️Pedal order inferred from interviews and typical metal signal chains; no studio photo of exact pedalboard for this track.
  • ⚠️Jim Root's gear is not included; this JSON focuses on Mick Thomson's main riff tone as per sources.
  • ⚠️No evidence of time-based or modulation effects in the riff section; only boost and noise gate confirmed.
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. Slipknot's 'Duality' features extremely high gain, tight low end, slightly scooped but not hollow mids, and aggressive yet controlled treble/presence for articulation. The tone is very dry and punchy, with no audible reverb, matching both the band's gear (Mesa/Boogie Rectifiers, EMG pickups) and early 2000s metal production.
