Notes & Caveats

  • ⚠️Exact pedal models for wah and delay are not confirmed in sources, but both are clearly audible in the solo section.
  • ⚠️Amp settings are taken from period-correct Mark IIC+ settings and interviews; minor variation possible due to studio EQ and multi-amp layering.
  • ⚠️No evidence of chorus, flanger, or phaser in the solo section.
  • ⚠️No evidence of additional boost or overdrive pedals in the solo section; distortion is from amp.
  • ⚠️Estimated reverb is based on typical Mark IIC+ use and forum settings.
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. For 'The Thing That Should Not Be' solo, Metallica used a heavily scooped, high-gain tone typical of their mid-80s sound (Mesa/Boogie Mark IIC+), with tight bass, pronounced treble, and minimal reverb for a dry, aggressive attack. The mids are set low for that classic 80s Metallica 'scooped' sound, and presence is boosted for clarity.
