01MOOER GE150 — High Gain Amp Model (5150 or Rectifier sim)
Use the GE150 as your PRIMARY gain source — select the '5150' or 'Recto' amp model. Run into the MG15G's CLEAN channel or use the GE150 direct into a cab sim/headphones. The MG15G's overdrive channel cannot achieve this saturation level.
02MOOER GE150 — Noise Gate
Essential for tight palm mutes — gate hard to kill string noise between riffs
03MOOER GE150 — Octave Fuzz (for intro only)
Engage only for the 'fucked up' intro riff — Mick's Kevin Allen fuzz is an octave fuzz with square wave filter
The MG15G's OD channel maxes out at medium-gain crunch — nowhere near 5150 saturation. Your GE150 is doing 100% of the heavy lifting here. I've set the MG15G to low gain as a clean-ish platform; if the GE150 has cab sim and headphone out, bypass the MG entirely for tighter response. Your RG421's Quantum humbuckers are hotter than Mick's DiMarzios, so I pulled GE150 gain back 1 point from the original 9.
