Papa Het's Hardwired Master Cores signature string sets have been co-developed with Metallica's James Hetfield over the past decade to best meet his demanding performance requirements. This set consists of James' preferred gauges using thicker Paradigm core wire with nickel-plated steel wrap wire and a proprietary Everlast nanotreatment. 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 reinforcement at the ball end for added strength and tuning stability.
