01Tube Screamer (TS9 / Maxon OD820)
RECOMMENDED — not currently owned; tightens low-end flub on down-tuned riffs
02Noise Gate (Boss NS-2)
RECOMMENDED — not currently owned; essential for Slipknot's dead-stop staccato muting
The Marshall MG30GFX OD-2 channel provides the necessary modern saturation, while setting mids around 4 delivers the aggressive 1999 self-titled scoop without getting lost. Your Ibanez Infinity R passive humbuckers lack the extreme compression of Mick's active EMGs, so treble is pushed to 7 to compensate for edge and attack. Note that the MG30GFX lacks a dedicated presence knob, so upper harmonics are managed entirely via the treble control.
