Notes & Caveats
- No direct numeric amp knob settings for the studio recording found; settings estimated based on typical Marshall JCM800 usage for 1980s glam metal and multiple forum/gear sources.
- No evidence of pedals or rack effects used for the main riff section; all distortion is amp-based.
- Pickup and guitar model confirmed for Warren DeMartini on 'Out of the Cellar' era, but not explicitly stated for every riff section—however, all reputable sources agree on the Charvel San Dimas with Seymour Duncan humbucker.
- Presence and reverb settings are estimated based on era and genre norms for JCM800 in studio use.
- If more specific studio notes or isolated track breakdowns become available, settings should be updated.
- Settings cross-referenced with genre and era conventions for accuracy. Ratt's 'Round and Round' features a classic 80s LA metal tone: high gain but not overly saturated, tight low end, scooped mids, and bright, cutting treble. Warren DeMartini typically used Marshall amps with the mids pulled back and presence/treble boosted for clarity, with minimal reverb for a punchy, dry rhythm sound.
