RECOMMENDED — not currently owned. The HB-20B's overdrive channel lacks the tight, aggressive saturation of a Mesa Mark series. A dedicated metal distortion pedal is essential to reach this tone. If using a pedal, set amp to CLEAN channel with gain at 2.

Why these settings

The HB-20B is a budget 20W practice amp with limited gain and a darker voicing than the Mesa IIC++. The Mesa's tight low-end and searing high-gain saturation cannot be replicated by the HB-20B's overdrive alone — you will get a mushy, undefined distortion. Treble pushed to 7 compensates for the amp's darker character vs the Mesa's aggressive top-end. Mid scooped to 3 replicates the Black Album's signature cut around 700-800Hz. Without a high-gain pedal, expect 40% of the original tone's tightness and aggression.

PRO TIPHetfield's tone relies heavily on extremely precise, aggressive down-picking with palm muting right at the bridge saddles — not near the soundhole. Dig in hard and keep your muting tight; sloppy technique will expose the amp's limitations more than any setting change.
