Ernie Ball RIP

Ernie Ball, a pioneer maker of rock 'n' roll guitar strings used by legions of artists from the Rolling Stones to Merle Travis, has died. He was 74.

Ball died at his home Thursday after an ongoing illness, the mortuary handling services announced.

His strings and instruments were used by music stars over the past four decades, from B.B. King to Metallica. Beginning with a small music shop in the San Fernando Valley, Ball built a business with annual sales of $40 million and a worldwide reputation. Along the way, he bucked traditional thinking in the music business.

"He changed the way people thought of guitar accessories, and how they sold and marketed them, and to this day the Ernie Ball way is the industry standard," his son, Sterling Ball, said in a statement.
