Why these settings

The Frontman 20G drive channel must carry the high-gain saturation since you own no pedals, so Gain is pushed to 8. Bass is kept at 6 to prevent the 8-inch practice speaker from flubbing out, while Middle is cut to 2 and Treble is set to 7 to emulate the Mark IIC+ classic 'V-curve' graphic EQ. Clean interlude: switch the amp back to the Normal (clean) channel with volume at 5.

PRO TIPLock in heavy palm-muting right at the bridge saddles and execute strict, aggressive downpicking on all low-E rhythmic chugs to match James Hetfield's signature percussive attack.
