Metallica’s James Hetfield launches signature guitar strings with Ernie Ball

Metallica frontman James Hetfield has teamed up with Ernie Ball to create his own line of signature guitar strings.

Dubbed Papa Het’s Hardwired Master Core, the strings come in a unique 11-50 gauge combo, which Ernie Ball calls “ideal for [Hetfield’s] aggressive style and technique.”

“It’s only taken 40 years for me to have my own strings!” Hetfield laughs in a video making the announcement.

You can order your Papa Het strings, which come in a tin box designed with artwork by Hetfield, now via Metallica.com. They’ll be available through Ernie Ball retailers beginning May 10.
