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!

Ernie Ball Cobalt Guitar Strings at a Glance:
  • Beta tested by the creme de la creme
  • Cobalt formula gives you higher output and better sound
  • Cobalts last longer
Beta tested by the creme de la creme

In the development of their Cobalt strings, Ernie Ball tapped select members of their star-studded artist roster - including Steve Morse, John Petrucci, Randy Jackson, Tony Levin, and Slash - to be beta testers for the new formulation. John Petrucci reported that the Cobalts sound "amazing," with "increased power, incredible clarity, and incredible sonic balance." He noted that the Cobalts seem "softer" under your fretting fingers (the term he used was "buttery"). Slash noted that - before being plugged in - the Cobalts "have an entirely different feel than normal strings." 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 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.

Cobalts last longer

Ernie Ball Cobalt guitar strings last longer, retaining their brightness long after other strings have given up the ghost. Steve Morse reported having a set on one of his guitars "for several weeks," and with daily use - "sweaty hands" and all - the Cobalts "still sound bright... They just don't have that dead sound," he says. So, with higher output, better sound, and the monetary benefits of not having to change strings so often, Cobalts have it all over traditional alloy formulations. Check out a set of Ernie Ball Cobalt strings - you'll love 'em!

Rated 5/5

Typical Ernie quality

Typical Ernie ball quality. I love the cobalt series, but the actual string guages was just a tad bit heavy for my taste. I'm going to drop to a little lighter guages as in the beefy skinnies and go from there.
Rated 4.5/5

My go to set!

These strings are one of the most important parts of my sound other than my les paul, as I am tuned down to drop B, and with that much slack, I need something heavy that can take the abuse, but still be thin enough to bend/depress, and these strings do the trick.
Without this set, I'd most likely be paying twice as much for a brand that I don't trust nearly as much.
My only two complaints are that the 24 plain is a bit of a pain to get used to and can buzz every once in a while, and that the 12 tends to be quite brittle in most packages that I've found, so I recommend always having a few spare sets.
Music background: played bass for a single practice session, and have been playing guitar for years. rock and metal.
Rated 4.5/5

Great for anything played with a dirt box

Just slapped these strings on my Les Paul trad and they sound fantastic. I play with a standard D/Dropped C tuning and the clarity these strings provide are completely worth the price. 9th and 13th chords are well defined. If you're familiar with that nice dry growl of a Warwick bass, well, it kinda reminds me of that. I'm interested to see how they hold up. If you play rock/metal, chances are good that these will work for you. As long as they last a while, I will definitely buy these again.

MUST BUY!!!

I went up to a music store in town and i decided to buy some cobalts cause i heard good things. There were right, i can guarantee you will get better output from these babies doesn't matter if it is power slinky or whatever you like, it is a whole lot better than regular nickel wound or stainless steel.
Music background: Guitarist for 6 years, drummer for 4 years, bassist for about 4
Rated 3/5

Solid strings!!

I loved this set! I just had to stop using them because the 24 is plain which makes zero sense. It's uncomfortably larger than a 3rd should be and goes out of tune (typical of unwound 3rds)
