Evidence

Why we think this is right

'Angry Chair' (written/sung by Cantrell) is from Dirt (1992, prod. Dave Jerden). Guitar is his 1984 G&L Rampage 'Blue Dress' (Duncan JB) [Ground Guitar; guitar.com]. In a 2022 Gearspace Q&A (quoted by guitar.com) Jerden details Dirt's layered rhythm rig — Bogner Fish preamp (lows), Bogner Ecstasy (mids), Rockman (highs), split via a Lucas Deceiver and miked with SM57 — plus a Mike-Moran-modified 1988 100/50W convertible Marshall Super Lead (6L6, extra preamp stage) for leads; Ground Guitar names the Facelift/Dirt Marshall as Bogner-modified. This chain condenses that into two documented, recognizable amp voices: the Bogner Fish 'brown' preamp for the heavy chorus and a Bogner/Mike-Moran hot-rodded 100W Marshall (edge-of-breakup) for the flanged clean/edge verses; both mods are GAIN mods (extra cascaded stage) so the stock JCM800/2203 model must NOT be used — map to a hot-rodded Marshall (Placater Dirty / Friedman-BE / Bogner 'brown'). The watery verse swirl is a flanger (MXR family). NOTE: there is NO talk box on 'Angry Chair' — the Heil talk box is on 'Man in the Box' only; it is deliberately excluded. Guitars are down-tuned (~half-step-down / ~Drop Db per common transcriptions). Cab = Marshall 1960B 4x12 (Greenbacks primary; G12T-75 / Vox bulldog cited on some layers), SM57 close. Amp EQ values are community-consensus 'match' settings, not factory-documented, hence modest confidence.
