Renowned Slinky strings with well-balanced tone and improved sustain.
Ernie Ball 2725 Cobalt Extra Slinky Electric Guitar Strings are widely revered for their world-class tone. The Cobalt Series is clearly an improvement on its classic nickel-wound counterpart giving the player increased sustain, clarity and output. In addition, they resist sweat and moisture better and have unmatched flexibility when compared to other nickel wound strings. Cobalt is the most magnetically active string alloy on the planet and attracts the magnets in your pickups more than any other string.
