Why these settings

The 72 Seasons rhythm tone is significantly more mid-focused and aggressive than classic 80s scooped Metallica tones, using the Mark IIC++ crunch with tight front-end boosting. On the Zoom G1 Four, select the BG MK3 amp block with the boost block in front cutting sub-bass and pushing upper-mids. Keep the Ibanez GIO's passive bridge humbucker volume at 10 to feed adequate signal into the virtual preamp.

PRO TIPAnchor your palm firmly against the bridge saddles and execute strict downpicking on the fast chugs — the percussive 'bark' of this tone comes directly from heavy right-hand attack right where the string leaves the saddle.
