Enter Sandman

Enter Sandman introduced a new, more polished Metallica rhythm sound. Hetfield's ESP through a Mesa/Boogie Mark IV with a scooped midrange and tight low end creates the punchy, percussive tone that defined the Black Album. Compared to the rawer Master of Puppets tone, Enter Sandman is more controlled, more produced, and heavier in the low end thanks to Bob Rock's production.
