Ernie Ball 2721 Regular Slinky Cobalt Electric Guitar Strings – .010-.046

Ernie Ball 2721 Regular Slinky Cobalt Electric Guitar 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.

The cobalt formula gives you higher output and better sound

A half-century ago, Ernie Ball practically invented “rock” guitar strings. And now, with Cobalt, they’ve re-invented them.

After exhaustive testing of over 350 alloy combinations, the company ended up with an optimal formula that – as compared with conventional strings – gives you higher output,

beefier lows with increased definition, improved midrange focus, shimmering harmonics, and more robust sustain. You get a brighter sound without inducing harshness by turning up the treble on your amp.
