Ernie Ball Cobalt Regular Slinky Electric Guitar Strings

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 guitar strings are also soft and silky to the touch, making string bending a breeze.
