Beta tested by the creme de la creme

In the development of their Cobalt strings, Ernie Ball tapped selectmembers of their star-studded artist roster - including Steve Morse,John Petrucci, Randy Jackson, Tony Levin, and Slash - to be betatesters for the new formulation. John Petrucci reported that theCobalts sound "amazing," with "increased power, incredible clarity, andincredible sonic balance." He noted that the Cobalts seem "softer"under your fretting fingers (the term he used was "buttery"). Slashnoted that - before being plugged in - the Cobalts "have an entirelydifferent feel than normal strings." He goes on to characterize thissensation as "bouncy and pliable," and "a lot of fun for bending." Whenamplified, Slash commented that the Cobalts were just as bright astitanium strings, but more "guttural," with more "growl to them."
Cobalt formula gives you higher output and better sound

A half century ago, Ernie Ball practically invented "rock" guitarstrings. And now, with Cobalt, they've re-invented them. Afterexhaustive testing of over 350 alloy combinations, the company ended upwith 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 thetreble on your amp.
Cobalts last longer

Ernie Ball Cobalt guitar strings last longer, retaining theirbrightness long after other strings have given up the ghost. SteveMorse reported having a set on one of his guitars "for several weeks,"and with daily use - "sweaty hands" and all - the Cobalts "still soundbright... They just don't have that dead sound," he says. So, withhigher output, better sound, and the monetary benefits of not having tochange strings so often, Cobalts have it all over traditional alloyformulations.
