Notes & Caveats
- No direct numeric amp settings for the studio recording found; amp settings estimated based on typical Marshall JCM800 usage for 1980s metal and forum discussions.
- Guitar model and pickup confirmed by multiple sources for the Holy Diver album era, but not explicitly stated for the riff section; inferred from period-correct interviews and gear rundowns.
- Boss SD-1 Super Overdrive is confirmed as the boost pedal for the riff by forum consensus, but no direct studio photo or interview for this specific song section.
- No evidence of time-based or modulation effects (delay, chorus, flanger, etc.) on the main riff; only overdrive/distortion is present.
- Presence and reverb settings are estimated based on typical Marshall JCM800 studio use; reverb is likely minimal or from room/console, but a small amount is included for realism.
- Settings cross-referenced with genre and era conventions for accuracy. Vivian Campbell used a hot-modded Marshall with moderate mids, tight bass, and prominent but smooth treble for a classic 80s metal tone. The gain is high but not extreme, with minimal reverb for a dry, punchy riff sound typical of early 80s metal production.
