Why these settings

The MG30FX OD-2 channel provides the necessary saturation to emulate Slash's hot-rodded Marshall #36 without external dirt pedals. Use the bridge humbucker on your GRX40 with mids pushed to 7 and treble kept at 6 to replicate the warm, biting bark of Alnico II pickups while preventing solid-state harshness. (Note: The MG30FX lacks a dedicated presence control).

PRO TIPDig in hard near the bridge with a heavy pick to trigger the signature aggressive harmonic bite on the opening riff, and switch to the neck pickup with tone dialed back to 6 if attempting the sweet solo tone.
