01Behringer Heavy Distortion (HM300)

This pedal is your primary gain source — it's an HM-2 clone which gives you the tight, saturated metal distortion the MG30's preamp cannot achieve alone

Level 7 · High 7 · Low 6 · Dist 8
Why these settings

The MG30GFX lacks the high-gain saturation and tight low-end of a Mark IIC+. Your Behringer Heavy Distortion becomes the gain engine — amp gain dropped to 3 to prevent mud from stacking two distortion stages. The MG's OD channel is mid-forward compared to Mesa's scooped character, so mids cut to 2 and bass pushed to 7 compensates. Your Harley Benton's passive humbuckers are lower output than Hetfield's EMGs, so the pedal's Dist at 8 compensates.

PRO TIPHetfield's tone lives in his right hand — strict downpicking with the pick angled slightly and palm muting directly over the bridge saddles. Loose muting kills this tone; keep your palm pressure firm and consistent. Tune to Eb standard.
