Notes & Caveats

  • ⚠️No direct numeric amp settings from primary sources for the original 'Eruption' studio recording; settings estimated based on period-correct Marshall plexi usage, genre, and era.
  • ⚠️All effects (delay, reverb) were applied post-recording in the studio, not via pedals or amp effects.
  • ⚠️No pedals or stompboxes were used in front of the amp for the riff section; all distortion is from amp and variac.
  • ⚠️Pickup is confirmed as bridge humbucker; no evidence of neck or other pickup positions used.
  • ⚠️Some sources list later EVH amps (5150, 5150III) but these were not used on the original 1978 recording.
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. Eddie Van Halen's 'brown sound' on 'Eruption' was achieved with a cranked Marshall Plexi, moderate bass for tightness, strong mids for cut, slightly tamed treble to avoid harshness, and moderate presence for clarity. Reverb is minimal, as most ambience was from the room or plate reverb in post-production.
