Built for power, precision, and absolute control - nothing less than you'd expect from James Hetfield.
Designed in collaboration with one of metal's most iconic rhythm players, the Ernie Ball Papa Het Hardwired Master Core strings deliver a tighter, more focused feel with serious low-end punch. Featuring a custom 11–50 gauge and Ernie Ball's Master Core construction, these strings are built to handle aggressive playing while maintaining rock-solid tuning stability.
If your playing leans heavily, whether it's tight rhythm work, downpicking, or high-energy performance, these strings give you the response and durability to keep up.

What makes Master Core strings different?
Master Core technology uses a heavier core-to-wrap ratio, resulting in a thicker tone and improved tuning stability, especially under aggressive playing.
Why are 11–50 strings good for heavy styles?
They offer more tension than lighter sets, making them perfect for tight rhythm work, downpicking, and heavier genres.
How do these compare to standard 10–46 strings?
11–50 provides a fuller tone, more resistance, and better tuning stability, particularly for heavier playing styles.
