Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings are a new spin on Ernie Ball's best selling set of strings which have been played by the likes of Eric Clapton, John Mayer, Steve Vai and many more. The Cobalt Series is clearly an improvement on its classic nickel-wound counterpart giving the player increased sustain, clarity and output. In addition, they resist sweat and moisture better and have unmatched flexibility when compared to other nickel wound strings. Cobalt is the most magnetically active string alloy on the planet and attracts the magnets in your pickups more than any other string.

"Ernie Ball Cobalt Strings sound and feel better than anything I've ever played! You have to check these out!" - Slash.
"Cobalt Strings feel incredibly silky under my fingers and deliver more punch, output, and clarity than normal strings!" - John Petrucci.

All Ernie Ball strings are precision manufactured to the highest standards and the most exacting specs to assure consistency, optimum performance and long life. Made in the USA.

I'll cut to the chase. As compared to the run-of-the-mill nickel strings... THE GOOD 1) Smooth feel 2) Slightly increased output 3) Better definition/clarity (bright, but not tinny/shrill) 4) Very good tuning stability - tuned up to pitch quickly and stayed there very consistently THE NOT-SO-GOOD 1) A bit pricey 2) Very small drop in "warmth" - didn't bother me much So I really liked these as compared to nickel strings. However, I use GHS Progressives. Compared to these, the Cobalts have fewer advantages. Tonally, I think they are on the same level. The Cobalts may have a bit more output and smoother feel. The tuning stability might sway me to these. I'll need to see how they hold up over time. Only 1 gig on the Cobalts so far, so I'll need to weigh-in on the longevity at a later date. That will also give me some time to refine my opinion as the strings "season". Definitely worth a try as they do provide non-trivial differences. Everyone has different tastes, so no better way to decide than for yourself!

Bought a 3-Pack of 10's. Right out of the package the 0.46 felt "Ruff" and Rusty, not smooth at all. All 3 packs had a similar "Ruff" almost "Tacky" feel on the 0.46, 0.36 and 0.26. The solid wire strings were quite smooth. Strung up my PRS Custom 24 to start, tried the Strat next. Clearly a much brighter tone than your typical Nickel wound string. Within a week the 0.46 on the PRS Custom 24 showed signs of what looked to be rust. This guitar was exposed to daily play and practice. Brightness seemed to decay on both instruments after a Month. Tone 5/5, Consistency 3/5, Quality 1/5. Verdict: Save your money, and go buy better Guitars, Pickups and Tube Amps instead.

Best strings I've ever put on an electric guitar

By Vincent Bath

from Salt Lake

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

I replaced the strings on a brand new Fender Stratocaster and the difference is more than substantial. Mine is the HSH model and sounded okay before. Now with the Cobalt strings each pickup change sounds like a different guitar. Fuller tones, remarkable clarity. I had no idea how good the pups were until I tried these strings. Wow!

never going back again

By stephen bauch

from dayville ct

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

When i first bought these strings i was let down. I noticed the output was higher but there was something that just didnt sound right. After a week i went back to the regular slinky nickel strings and i was stunned by how bad they sounded. They sounded lifeless. No punch at all and i had to turn my amp up to get the same output as the cobalt strings. 2 days later i put the cobalts back on and wont look back.

Increased Clearity

By Alex Augustus

from Rockville Conneticut

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

These strings are truly amazing. They sound and feel better than any other Ernie Ball string. Better clarity and a very tight low end. It's amazing how you can hear each note perfectly.

Wow, What a Difference!

By Carl Tripodi

from Annapolis, Maryland

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

I installed these strings on my Fender Strat with passive Seymour Duncan pick ups, and wow what a difference did these strings make. The guitar sounds more aggressive and detailed. I used to have to pound on the strings when doing hammer ons in order to hear every note, with the Cobalt strings, I do not. These will be my strings of choice from here on out. These are the best strings I have ever installed on my Strat.

A little disappointed, really

By Jim Adams

from Peoria

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

I installed these strings on my guitar approximately a week ago on my Schecter C-1 Classic, and quite frankly, I did not feel as if they were worth all of the hype. They did not *feel* silky and superior, but felt rather rough and prohibitive in even the simplest of moves. I suppose the midrange response was a little more pronounced, but, for me, the pro's did not outweigh the con's of these strings. I switched back to Ernie Ball Reular Slinkies, and am by far happier with the end product.

NOT silky or smooth

By John Tinsley

from St. Louis Missouri

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

Big letdown. Strings feel sticky & dry. They do not feel smooth & silky as advertised. I agree that they do produce more output & better sustain but not enough to justify the price or lack of feel. I will be going back to my regular slinky's.

Over-hyped?

By Timothy Myers

from Ohio

Comments about Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings:

It was with a fair amount of anticipation that I awaited the arrival of these strings. I'll cut to the chase - I found them to be overly-bright and rather harsh sounding, especially with single coils. Better with HBs and the tone rolled way back, but still not the sound I was hoping for. On the plus side, they do bend nicely and produce decent sustain. I didn't find them to be "dry" or "sticky" at all - quite smooth. Anyway, they're okay but certainly not the "holy grail" of guitar strings.

Oh my goodness! These strings are the cat's meow. Best string I've ever played in my 36 years of playing guitar. Buy a set and you won't believe your ears.
