Notes & Caveats
- No direct numeric amp settings for Geek U.S.A. riff found; settings estimated based on Marshall JCM800 typical use in Siamese Dream era and genre.
- Pedal order and exact settings inferred from multiple sources and audio analysis; no studio session sheet available.
- Creamy Dreamer pedal is a myth for this recording; confirmed not used on Siamese Dream.
- No evidence of amp reverb or delay used on riff section; all ambience is studio/mix.
- Exact pickup selector not documented, but bridge humbucker is standard for heavy rhythm on this album.
- Settings cross-referenced with genre and era conventions for accuracy. Billy Corgan's 'Geek U.S.A.' tone is extremely saturated, mid-forward, and aggressive, typical of early '90s Pumpkins using high-gain Marshalls (JCM800/900) with mids and presence boosted for clarity and punch. The tone is very dry (no reverb), with tight low end and pronounced upper mids/treble for cut, matching both the band's gear and Butch Vig's production style.
