OVERVIEW

Hear your solos like never before.

Ernie Ball 2715 Cobalt Skinny Top Heavy Bottom Slinky Electric Guitar Strings are the perfect hybrid set for those who like thick bottom strings without sacrificing the ability to solo on smaller strings. 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.
"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.

I've been playing for 15 years, have a degree in music, and transcribe music on a normal basis. The reason I bring this up is because I have finely tuned my ear over the last 15 years. I was a GHS guy for the past 15 years because of the even tone, the strength of the string, and how well they stay in tune. Ive tried Ernie balls and hated them with a passion. Ive been using the new cobalts for a couple days and cannot say enough good things about them. There is a VERY noticeable difference in output. One thing i saw as a complaint on one of the other reviews is that they dont stay in tune very well and that theyre floppy, this is the absolute opposite of the truth. While its true that they seem to be a bit more elastic, this actually keeps them in MUCH better tune. I my guitar into a strobe tuner, which if you dont know is about the most accurate tuner you can buy(check out peterson strobe tuners or if you have a smart phone, check the app store) and it doesnt matter how hard you hit them, they barely go sharp if at all. I had to pluck the string as hard as I possibly could before it would go sharp. Ive never played anything like it. I still want to try GHS progressives but they dont come in this gauge. Needless to say until GHS comes out with a cobalt string, Im an Ernie Ball man.

I've been using Ernie Ball strings for over 10 years. The first thing I noticed about these strings after I put them on my main axe was that they did not have the flexability of the regular Slinky's. I tend to bend alot when I play, and I have been annoyed by a lack of smoothness in my bends. I played a rehearsal and one gig with them on, and there is already a decent ammount of wear on the wound strings. It usually takes me a few weeks to get wear with nickel slinky's. They do sound brighter unplugged or on a clean setting. For me it'd be a different story if they weren't charging almost double for these strings or if they weren't overhyping their slightly higher output. It was a fun experiment, but my results don't warrant me ever trying these strings again anytime soon.

          I tried the Cobalts on my Strat, and think that they are the best thing since sliced bread. VERY responsive, really make my standard pickups, which I was about to upgrade, come to life. Think I'll hold off on the upgrade a while longer.

            These strings are great. I use them for Drop B. They last long and can handle a lot. I've never had any string that was part of the cobalt series snap on me, so they are very reliable. The only complaint I have is that they take some time to break in.

              Comments about Ernie Ball 2715 Cobalt Skinny Top Heavy Bottom Electric Guitar Strings:

              Needed a set of strings in a pinch so I picked these up. They are VERY bright sounding. They are the brightest sounding strings I've ever purchased. They have a very typical feel about them, so no smooth "elixir strings" style feel.

              They are obviously well made and handle abuse quite easily. The biggest drawback to them is when it's time to change the strings, you will really know it -- The tone becomes so flat and lifeless it is embarrassing.

              Excellent strings overall, some of the best I've ever used. They don't break easily and sound great (until they are over used!)

                    These strings totally suck compared to the other ernie balls. I use the same size(lite top/heavy bottom) and figured I'd try these. They are way too rubbery in response, doesn't hold the note played in tune as well, specifically if you tune down at all below standard E. Like I read in a previous review, I'm just going back to better ernie ball strings that sound, feel, play better and better at maintaining tuning.
