Enter sandman amp settings — Harley Benton HB-20R

The Metallica guitar tone for “Enter sandman”, dialed in for a Harley Benton HB-20R with a Donner DST-550. Studio version, Metallica / The Black Album (1991) — iconic heavy rhythm riff

Original rig

ESP MX-250 Explorer with EMG 81 active pickups into blended Mesa/Boogie Mark IIC++ (primary, scooped 5-band EQ) and Jose Arredondo-modded Marshall JCM800 2203 with Aphex parametric EQ in FX loop

Massive, tight, percussive high-gain rhythm crunch with deeply scooped 800Hz-1.2kHz midrange and razor-sharp palm-mute attack

Why these settings

The HB-20R has a simple solid-state analog preamp with 3-band EQ and built-in spring reverb, but no presence knob. Setting the amp to its Overdrive channel with Gain at 7 and Mid cut to 3 mimics the classic Mesa IIC+ V-curve scoop without making the 8-inch speaker fart out on low palm mutes. While this provides the best possible riff saturation using only your amp, adding a dedicated distortion pedal into the clean channel will dramatically tighten up the low-end punch to match Hetfield's quad-tracked wall of sound. Clean intro: switch amp channel select OUT to Clean and roll guitar volume to 7.

PRO TIPAnchor your palm firmly against the bridge saddles and execute every rhythm note with aggressive, uniform downstrokes — Hetfield's mechanical precision and right-hand attack define this riff far more than raw gain saturation.
