Why these settings

Per double-gain prevention, the owned Suhr Riot Reloaded serves as the primary high-gain engine into the Mooer GE150 with amp block gain dialed down to 2. Your EMG-loaded Jim Root Telecaster already supplies the tight active output James Hetfield used, so the amp model's mids are scooped to 3 to recreate the Mark IIC+ graphic EQ V-curve without getting muddy. Clean interlude: bypass the Suhr Riot and switch to the GE150 clean twin model with onboard chorus.

PRO TIPAnchor the meat of your picking hand right over the bridge saddles and execute strict downstrokes with heavy attack; Hetfield's percussive chug comes entirely from down-picking violence compressing against the active EMG 81.
