Notes & Caveats
- No explicit amp knob settings for 'Sassafras Roots' found in sources; settings estimated based on Marshall JCM900 typical punk usage and Dookie-era context.
- No evidence of pedals or effects used on the riff section; all distortion is from the amp.
- Pickup choice inferred from Billie Joe's known use of bridge humbucker for rhythm on Dookie.
- No evidence of effects loop or additional modulation/time-based effects for the riff section.
- All settings and effects are for the studio recording, not live.
- Settings cross-referenced with genre and era conventions for accuracy. Billie Joe Armstrong used a Marshall Plexi (often with a Tube Screamer boost) for Dookie, aiming for a crunchy, mid-forward punk tone with tight low end and moderate treble. The riff is dry and punchy, so reverb is minimal; mids are pushed for clarity and aggression typical of 90s punk rock.
