Papa Het’s new hardwired Master Core signature string sets 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 James’s preferred 11-50 gauge combination using thicker Paradigm core wire and plasma enhanced nickel-plated steel wrap wire. They are ideal for James’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 graphics and artwork designed by James! The tin box is compact, highly collectible, and includes three signature string packs inside.
