01Boss MT-2 Metal Zone (or similar high-gain distortion)

RECOMMENDED — not currently owned. The Frontman 20G cannot produce high-gain metal distortion on its own; a dedicated metal distortion pedal is essential. Boss MT-2, MXR Fullbore Metal, or TC Electronic Dark Matter are budget options that will get you there. Run into the amp's clean channel with amp gain at 2.

Why these settings

The Frontman 20G is a solid-state practice amp with limited gain and no high-gain voicing—it cannot replicate Mark IIC+ saturation on its own. I maxed the amp gain and scooped mids to get the closest approximation, but the tone will be thin and fizzy without a distortion pedal. Your Les Paul's Burstbucker Pro pickups are hotter than passive single coils but cooler than EMGs; I dropped treble slightly from the original and boosted bass to compensate for the warmer humbucker voicing. A distortion pedal is mandatory for this tone.

PRO TIPHetfield's tone lives in his right hand: strict downpicking with the pick angled slightly, palm muting right at the bridge saddles. Practice the main riff at 60 BPM with a metronome, all downstrokes, before speeding up—the percussive attack is 50% of the sound.
