The most popular Slinkys with a Cobalt twist.

Ernie Ball 2723 Cobalt Super Slinky Guitar Strings are round-wound for maximum clarity and serious punch. The Cobalt Super Slinky set 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.
"There's a certain degree of clarity and punch you get from Cobalt Strings that I haven't heard tonally from any other strings I've played." - Joe Bonamassa.

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.

Gauges: 9-11-16-24w-32-42.

  • Love them

    As reviewed by Isaac Stuckey on 8/9/2012

    These strings feel great under my fingers and they make my strat just ring out WAY better than they did with D'addarios. The guitar is louder with better response and I love it. As I've said before, there is not really a better when it comes to guitar players. It's ALL opinion based.

  • Best Strings Ever

    As reviewed by Paul Edwards on 8/23/2012

    I tried these strings about a month ago and was overwhelmed by how they sounded and felt right away. Totally blown over. It was like putting new pickups. That's how dramatic the change was. I promptly changed to these strings on all my electric guitars. Never felt so much about a set of strings and you should do yourself a favor and at least try one set and you will soon change over to these on all your electric guitars. Sincerely the best improvement in basic gear over the past ten years.

  • Holy Shit! OMG!!!

    As reviewed by EDDIE VELASQUEZ on 5/12/2012

    More output indeed! Big difference in sound and it makes my Gibson Les Paul come alive when it was hooked up to my tube Fender amp. People have to try this new product because it sounded great on the clean channel and it feels great under my fingers.
