Why these settings

ME-90's RECTI amp model replicates the Mesa Rectifier scooped aggression from the original layered rig. Mid scooped to 4 (vs original 5) because ME-90's Rectifier voice is already forward in that range. Presence at 7 matches the recorded bite. For the clean intro, roll your guitar volume back to 4-5 and pick lightly—do NOT switch amp models mid-song; the dynamics come from your hands and volume knob.

PRO TIPTune to drop C (C-G-C-F-A-D) and use palm-muted 16th-note picking on the low C string for the main riff—the tightness comes from pick attack consistency, not from additional gating or compression. Let the notes ring slightly between mutes to preserve the original's percussive groove.
