Studio recording, 1992 (Dirt album). Jerry Cantrell used the G&L Rampage with the bridge humbucker for most heavy rhythm tracks on Dirt, including 'Junkhead' riff. The amp setup was a Bogner Fish preamp into a Marshall JCM800 head, as confirmed by Cantrell in interviews and Equipboard. No evidence of live rig or alternate guitars for this section.

Notes & Caveats
- No direct numeric amp settings for 'Junkhead' found; amp settings estimated based on typical Bogner Fish/Marshall JCM800 usage for 1990s grunge/metal rhythm tones.
- Pedal usage for the riff section is inferred from sources and audio; no explicit studio notes for pedal settings or effects chain for this song's riff.
- No evidence of modulation, delay, or time-based effects in the riff section; fuzz/distortion is from amp and/or Big Muff, but Big Muff is more associated with solos/leads.
- Pickup choice inferred from G&L Rampage's single bridge humbucker configuration.
- Guitar knob settings estimated based on typical usage for Cantrell's rhythm tone.
- Settings cross-referenced with genre and era conventions for accuracy. Jerry Cantrell's 'Junkhead' tone is thick, mid-forward, and saturated but not overly scooped or fizzy, reflecting his use of high-gain amps (Soldano SLO, Marshall) with mids pushed and a dry, in-your-face production typical of early 90s grunge/metal. The bass is tight but not boomy, treble is present but not harsh, and reverb is essentially absent in the main riff section.
