Studio recording, 1989-1990 for 'Passion and Warfare'. Vai used his Ibanez JEM77FP with DiMarzio PAF Pro pickups into a Carvin X-100B head and 4x12 cab. Effects were primarily rack-based but emulated here with pedals for clarity. Settings and effects are for the SOLO section (distorted, singing lead).

Notes & Caveats

  • ⚠️Exact pedal models for the original studio recording are not fully documented; pedal choices are based on era-accurate gear and forum consensus.
  • ⚠️Amp settings are averaged from forum posts and typical Carvin X-100B usage for Vai's 1990s lead tone.
  • ⚠️Delay, chorus, and phaser are clearly audible in the solo, but specific rack units used in the studio are emulated here with common pedal equivalents.
  • ⚠️Presence setting is estimated based on typical Vai/Carvin X-100B usage; not directly cited.
  • ⚠️Vai's actual studio effects were likely rack-based (Eventide, Lexicon, etc.), but pedal equivalents are listed for clarity.
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. Vai's 'For the Love of God' solo tone is saturated but articulate, with a smooth high-gain lead sound, prominent mids for vocal sustain, tight but not boomy lows, and clear but not harsh highs. The presence is set to add air without fizz, and reverb is moderate, as most ambience is from post-production rather than amp spring reverb.
