Why these settings

The MG50FX has no physical presence control, so presence is nulled. Pete Loeffler tracked massive Drop B riffs through a Mesa Dual Rectifier, which naturally scoops around 800Hz and produces loose low-end; pushing your MG's mid to 6 prevents thinness while your owned Mooer GE100 acts as a clean mid-boost with drive near zero to tighten the low strings. Keep the MG50FX on OD-2 with gain at 7 so the amp provides the cascading distortion without muddying up your Epiphone SG's humbuckers. Verse clean-up: roll guitar volume back to 4-5 and switch pickup to neck.

PRO TIPChevelle tracks 'Jars' in Drop B (B-F#-B-E-G#-C#); use heavy-gauge bottom strings (at least .054 or .056) and dig into the palm mutes right near the bridge saddle to keep the low B percussive rather than mushy.
