6 PACK OF ERNIE BALL COBALT SUPER SLINKY ELECTRIC GUITAR STRINGS!

Next-gen Guitar Strings Ernie Ball Cobalt guitar strings are made of a new alloy formulation that gives you higher output, better sound, and longer life. Cobalt strings' special iron/cobalt blend attracts the magnets in your pickups better than any other alloy. When you string up with Ernie Ball Cobalts, you'll immediately notice the incredible comfort these strings offer - silky and pliable under your fretting fingers; your pick will seem to glide over the strings, letting you execute fast passages effortlessly. And when you plug in, you'll get increased power, beefy yet defined lows, improved midrange focus, harmonics, and sustain, and crisp highs. Try a set of Ernie Ball Cobalt strings - you're gonna love 'em!

He goes on to characterize this sensation as "bouncy and pliable," and "a lot of fun for bending." When amplified, Slash commented that the Cobalts were just as bright as titanium 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" guitar strings. And now, with Cobalt, they've re-invented them. After…
