Developed with Metallica's James Hetfield over the past decade, this signature set consists of James' preferred 11-50 gauge combination using thicker Paradigm core wire and plasma-enhanced nickel-plated steel wrap wire. They are ideal for James' 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.
