„For my playing I need heaviness and a full tone for higher frequencies. Due to the strong magnetism the output of Ernie Ball Cobalt strings is magnificent. Their sound and quality fit my needs perfectly.“ – Linus Klausenitzer

Ernie Ball, the worldโ€™s leading manufacturer of strings and accessories, has been making high-quality electric guitar and bass strings since 1962. World-class players like Paul McCartney, Keith Richards, Eric Clapton, Slash, Jimmy Page, and Buddy Guy have all played Ernie Ball strings to create their unique sound.

Cobalt strings provide an extended dynamic range, incredible harmonic response, increased low end, and crisp, clear highs.
Cobalt provides a stronger magnetic relationship between pickups and strings than any other alloy previously available. Cobalt Slinky bass guitar strings are also soft and silky to the touch, making string bending a breeze.
