Papa Het’s new hardwired Master Core signature string sets from Ernie Ball have been co-developed with Metallica’s James Hetfield over the past decade to best meet his demanding performance requirements. This signature set consists of Hetfield’s preferred 11-50 gauge combination using thicker Paradigm core wire and plasma enhanced nickel-plated steel wrap wire. These Ernie Ball strings are ideal for Hetfield’s aggressive style and technique, offering a heavier sound with extra pitch stability.

The Plain strings consist of Paradigm core wire with brass RPS reinforcement at the ball end for added strength and tuning stability. These limited-edition signature sets are housed in a durable tin box with custom “72 Seasons” graphics that celebrate over 42 years of Metallica.
