Why these settings

The MG30FX's OD-2 channel acts as the primary gain engine, pushed hard to mirror the raw clipping of Kirk's solid-state Randall. The Boss OS-2 is set with minimal Drive and elevated Level to act purely as a front-end tightening boost rather than an independent dirt stage. The MXR 6-band EQ carves out the mid-range boxiness around 400Hz–800Hz while pumping 100Hz to replicate the colossal cab resonance of B-standard tuning. Note that the Marshall MG30FX faceplate lacks a presence control.

PRO TIPDown-tune your Explorer to B Standard (B-E-A-D-F#-B) with heavy gauge strings (at least .012–.056) and hit the strings hard near the bridge with a rigid, heavy pick to get that signature percussive, grinding attack.
