Metallica · reviewed by the Change Your Strings editorial team ·
James Hetfield has used Ernie Ball Regular Slinky (.010–.046) for the majority of Metallica's catalog in E standard and Eb standard. For tracks in Drop D he has reportedly bumped to .011 sets. For lower tunings on the Black Album era and later work in Drop C on newer albums, heavier gauges including .011–.054 have been used. He is a long-time Ernie Ball artist.

What's on the guitar
James Hetfield's string choice has been remarkably consistent across Metallica's 40+ year career. The core of his rhythm tone is:
- Strings: Ernie Ball, typically Regular Slinky (.010–.046) in E standard and Eb standard.
- Tuning: Eb standard is the Metallica default for most of the catalog. Some material is in E standard. Drop D and Drop C appear on specific tracks.
- Gauge adjustments for lower tunings: Heavier sets (.011 and up) when the song calls for Drop C or below.

Endorsed vs. verified use
Hetfield is a documented Ernie Ball endorser. He is also a verified user: interviews with him and his guitar tech have consistently referenced Ernie Ball sets. The endorsement and the actual use align, which is not always the case in this industry.
Why Regular Slinky for a metal rig
Bedroom metal forums love to argue that metal requires .012 sets. Hetfield's career is a counterargument. Nickel-plated steel in a .010 gauge, picked hard into a high-output humbucker (EMG JH Set) and a tight gate, is responsible for some of the most recognizable rhythm tones in rock history.
The takeaway: gauge matters less than picking attack, amp voicing, and gate discipline.
