OVERVIEW

Play like a pro with these revamped classics.

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.

Actually I am somewhere between Novice and Experienced. I had been using a variety of strings and was okay with a couple of brands. But then I tried these and I was surprised at the sustain these gems had compared to the name brand strings I had been using. I love them. IF there are others I want to know, but these have sustain and clarity I hadn't been getting until now. Just wow.

I've been a D'Addario user for the last 10 years; however, I was curious about the new Cobalt strings introduced by EB, because no other string manufacture ever marketed strings made from this metal. When these new EB Cobalt strings were placed on my Fender Highway 1 HSS Strat, I noticed the guitar had much greater dynamics, volume, sustain and tone compared to the regular D'Addario 10-46 used in the past. Even when strumming the electric unplugged, you can definitely feel the energy of the sustain, and hear the dynamics of the individual notes clearly. These traits were also experienced with the guitar being amplified clean and dirty. Because of the strings clearity, you will hear all the nuiances of your playing. So if you play sloppily now, you hear that with these strings. But over time, your playing can become much more precise. As for feel, there seemed to be more drag when sliding. It wasn't as smooth as the D'Addarios. After 3 hours of playing, my fingertips were more chewed-up than playing with the DA's made from nickle. With that said, I also noticed that my guitar frets started to wear down quicker over the last year. Perhaps Cobalt is a harder element than Nickle??? As far as durabily is concerned... the plain strings started to tarnish after about 2 weeks, but tuning, tone, sustain, dynamics and volume were maintained. After about a year, I switched back to DA's because of the fret wear and draggy feel. I will try these on my guitars with stainless steel frets, but will not put them on my regular nickle alloy fretted guitars.

If EB can make these strings with less drag on my fingers, less wear on my frets and ant-tarnish, then that would more justify the price. Till then... I'm going back to D'Addarios.

Best Strings Ever Produced....

By Jamithome

from California

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

I was a little skeptical, but these are by far the best strings I've ever played. I won't be using nickel any longer!
Just bought a few packs of these Cobalt Regular slinky strings and put them on my Strat and Les Paul, and I've never heard my guitars sound so good. The output and clarity, especially in the mid range is so much better than nickel. Great job EB.
Great strings, holding up well too!
Worth every penny in my opinion. My guitars finally have a new voice!

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

I was disappointed when I went to my local shop and all they had were sets of 9's. I haven't played on anything less than 12's since I first picked up the guitar. Imagine my surprise when I got them on and it sounded like I had 14's on, yes they sounded that fat. After playing 12's for the past 3 decades my fingers were flying up and down the fret board like lightning posessed. Light, fast & they sound like they're fat enough to hang a truck on without breaking. I play a U.S. Telecaster through a Fender Blues Deville with 4x10's that is so clean that I have to be up around ear bleed volume to get even the slightest overdrive. These strings deliver something I thought I'd never accomplish without a series of OD pedals. Thanks Ernie Ball. What I will save in not having to keep buying OD pedals should set me up with enough strings to last the rest of my life.

About Me Experienced

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

I've been using Erine Ball Regular Slinky Nickel strings for 20 years and love them. I recently wanted to try the new cobalt strings on my Les Paul. The first set I used at home and at a few indoor gigs and was pretty happy. They weren't as bright as Regular Slinky's, but that was what I was going for with my Bluesy Mid rangy tone. I put a second set of cobalts on my les paul and played an outdoor gig in the summer time in MN and was so disapointed at how fast these cobalt strings corroded in the humidity. They were dead in one day of playing outside.... Sorry but I won't be buying cobalts anymore. Nickel forever!

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

I have never used regular Ernie Ball slinkys so I cannot compare the two....With that being said, on to my review!
I tried these when they came out after using Elixer Nanowebs for years. The Cobalt EB's sound better to me and strength wise are just as durable. And they don't get "fuzzy" from a coating coming off that you don't need any way.
I practice 2 to 3 nights per week, and we play 4 to 6 shows per month (4 hours a night). I sometimes keep my axes in a case, and sometimes they may hang on a stand for a week. They don't rust and sound great..... I know I should change more often, but, I generally only change strings once a month.
They stretch out and break in quick, (like right before a show LOL), stay in tune, and, in the 2 years I've been using them I have not broken one
yet.
I play a Fender Strat, and a Jackson dinky with a Floyd Rose.

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

I have used standard 10-gauge Slinkys ever since I first used an electric guitar. When I heard the comments on these things from Steve Vai, Steve Morse, Paul Gilbert, Slash, Steve Lukather, and of course, John Petrucci, I new I had to get some.
First off, the tone. Breathtaking! Clear, shimmery tone, and very clean and open sounds that ring forever. Sustain is great, and it does not go away easily.
Secondly, the feel. Honestly, the feel is pretty different. The winds are a little bit wider apart then standard strings, and this does make them a little more grimy feeling. There is more of a scratch when you slide up a not. That being said, these strings can last forever, and they actually do feel very good. The thing is, they feel very nice and silky most of the time. Recently, the packs I have gotten are just a little grittier for some reason. Also, they normally will feel very strange right out of the pack, and this is where you will find the squeaks and grimy feel. But in the many packs of Cobalts I've gone through, that goes away in a couple of days, and they feel very nice for months afterwards.
Overall, these are the best strings I've ever played. I will continue to use these for as long as I can. Be warned though; they do feel very different, sharp almost, straight out of the pack, but don't remove them. They will be much better in a couple of days.

Too bright sounding to me

By Something Wicked's drummer

from West Virginia

See all my reviews

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

I put these on an old ESP LTD MH-400 with EMG 81s.The stirng are way too bright to my ears. They almost sound harsh to my ears. I think they would sound much better on a guitar that has single coil pickups like a strat or a tele. They have a snappy, very very bright, bell-like tone to them. I personally perfer the sound of a nickel string. I would recommend trying them for yourself. You may like the way they sound on your guitar.
They do slightly increase the output of your guitar and give you sligh more clarity.
They seem to be holding up well. I have been playing them for a few days know and they are still and bright as when I first put them on.
They are too expensive for what you get. They are only a little bit better than nickel strings. In my opinion it is not worth paying twice as much.

Worth a look

By jpmct

from Virginia, USA

See all my reviews

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

They improve the tone of my Ibanez than I use for hard rock songs and they are fast and playable. They enhance the tone of the instrument. For a strat, they add treble and edge, so that's better if that is what you are looking for. You do lose a bit of the classic strat quack. For Les Paul's I don't like them. LP's are a dark guitar and it makes it sound different. If you are playing rock on the LP it would be fine, but if you are playing alternative or blues numbers I think it sounds worse, at least to my ear.
The use of a Cobalt alloy gives the strings different handling and magnetic properties that changes the feel and the tone of the product. This is certainly true. The strings have a smoother texture, are audible louder and change the tone of the guitar. The frequency response captures more high end and is is easier to achieve intentional harmonics. Sustain is improved, but I suspect this is merely because they are louder. It would be nice to have a bulk package as pulling them out of individual packages is a pain when you are trying to striing the instrument quickly on a workbench.
Packaging and pliability are fine. I can't comment on string life other than to say that that I have used them for three gigs in the past two weeks and they still sound new. This is no different than the D'Addario's that I usually use.
They are reasonalby priced.

Cobalt Regular Slinky Electric Guitar Strings- by William D.Jones

By william jones

from Orlando, Florida

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

i think these strings are a milestone in guitar history and think that these strings will go about for some time now wtih an ok price good feel, surprising new tone and overal satisfaction it seems to give you
Just got these today when i first opened then i first noticed totally new envolopes for strings. At first glance you couldn't really tell the difference from a normal nickelwound set until you feel them. they aren't as rough as normal and kinda remind you of presure wounds at least in my opinion.
To me it seemed like these were made for professinals and it gives you a professinal feeling.You tend to get more tone it seems from the low E A and D strings, and when playing i noticed that you could get harmonics from every fret, which i thought was cool not to mention the improved pinch harmonics that metal calls for.
i think Ernie ball made just the E A and D string from the alloy, which i think is kinda cheap but what ever it was an ok price i suppose, then again i had to test them for myself and the price wasn't that extraordinary

Good but expensive

By Jonathan Martin

from Georgia

See all my reviews

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

These cobalt strings do sound and feel better on my guitar than regular strings. My guitar has slightly more output and is more responsive with cobalt strings on it. My only problem with them is the price. It is hard for me to justify paying over twice as much for strings when the results aren't that different. Unless they lower the price a bit, I believe I will stick to normal strings for playing live or practice. The only time I would be tempted to use them again would be recording, where the difference might be more obvious.
They're stings, not many features they could put on them.
Can't complain about the quality at all. These strings feel very nice and I have no reason to doubt that they will last.
The price is just too high. I'm sure the r&d costs demanded a high price, but regular strings cost half as much without a huge loss in sound quality.

      I got a few packs of these over a week ago at my local music store because they were the only 10s they had so I figured I'd give them a shot. Every set I tried sounded like a set I'd used for 10 years they were so dull! The wound strings felt like rusty barbed wire under my fingers and the plain strings felt really raw and sharp like they were cutting my fingers. With no other choice I had to use these strings for 3 gigs. I will NEVER use these strings again!!

        These are some great sounding strings. For years I have used the Markley Blue Steel. Those are great stings as well. But these Slinkys have a louder sound and a much better tone. Also, they seem to stay in tune very well. I am using them on my Godin SD and I believe these strings gave that guitar a whole new tone and feel. I do a lot of bending and I pick with a Dunlop Jazz3. They have held up very well. I am really glad I tried them. Now I am hooked on them big time.

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

          I expected a overly brite tone, but a singing quality is what comes out and not harsh like I thought it would be on my single coil pups.
          My regular strings are fine but these are the bomb.
          The sustain is exceptional and the crunch is awesome with a great bottom end.
          Clean is again fabulous,i don't have issues with them getting dirty or hard to slide .
          After I was playing a couple weeks my roommate tried them and was surprised as well on the clarity with our tube amps.
          I gave him a set because I was couldn't belive how alive they seemed to me.
          I wasn't imagining things,these strings ring tone like no other string.
          I had brite strings before that were harsh,but the highs are more harmonic than harsh on the cobalt ,its hard to describe.
          They slam the lows perfect and ring out beautifully on the highs,the mids are fine as it gets.
          They just have such a wider range of dynamics its apparent these cobalt strings has more of everything good that I like about the sound of strings.

          I bend abunch and play slide so ive tested these out,they stay in tune with little breakin also.

          You can hear the difference without a amp if its quiet , very noticeable at 3am when I put um on !
          Again I thought they would be real brite,but that singing tone just rang out just right.
          Amazing is what I found , slide does sound tremendous.
          I tried on my guitar w/humbucker sized single coils and with a 2-12" wizard and tonker cabinet !
          I was surprised my impression on how they play as I had read complaints about dirty sticky fingers and hands and really wasn't expecting a great playing string like I found.
          Jez every guitar plays different maybe,but mine sound and play great !
          No whinning here,these strings sound great !

            I tried these out on an American HSH Ash Strat. I did not like them at all. Yes, the output is higher, as advertised, but it was too much higher for my taste. The humbuckers on my HSH strat (Twin Head Humbuckers) became very muddy with these strings. I WILL say that the output of the middle single coil pickup was increased in a good way....I removed the strings after a couple of days and replaced them with regular Ernie Ball slinkys, which I normally use. I did not test these strings on my Les Pauls, but I think the results would be similar. My take on these strings - they could benefit guitars with single coil pickups if you want a little extra oomph.....for guitars with Humbuckers, unless you set your pickup height very low, you may not like the results.

                They sound really good but the wound strings feel dry and rough. There's a lot more string noise but it doesn't seem to come through the amp at all. Not much of a difference from the regular slinkys, other than feel/string noise and the price tag. But a lot of people seem to like them. Couldn't hurt to give them a try.

                OK, let me start out by stating that Im not just a bedroom guitarist. I have been playing for the better part of my life. I have worked in a profesional studio environment as well as live shows, and even had radio play. I LOVE regular Slinkys. I only tried these on the very strong suggestion of the sales person at my local music store. I strung up my 2003 PRS Custom 24 and plugged into my Mesa Dual Rectifier, and emmediatly thought some one messed with my EQ controls. The sound was WAAAAAY brighter than Im used to. And my PRS lost TONE. I mean these strings were a bit louder than regular slinkys, but they sounded horrible! If you have a guitar with muddy pickups, or you drop tune for metal, than maybe these will work for you. I will NEVER buy these again, and Im furious that I spent 2x the cost of normal Slinkys for these! And they feel much less smooth. You get more finger noise when sliding than normal Slinkys. If you already use regular Slinkys, stick with them. AVOID THESE AT ALL COST!!! >:(

                I strung up my 62 jazzmaster with these having rather high hopes. I strummed a chord and was immediately deflated. After I put these on, the rich creamy jazzmaster tones I've grown to know and love were completely unattainable. Just bright and punchy and punchier and brighter. Some players might dig that with their jazzmaster but not me.I went running back to elixer wondering how i could have ever betrayed them.

                But I wasn't ready to give up on these strings yet so I tried a set on my ej strat. Completely different reaction! The tone, clarity and depth were great. Not sure they were better or worse than elixers, but they sounded good so I didn't overthink it.

                As far as feel goes they're pretty nice. For me though nothing slides and feels quite as nice as elixers. My hands sweat quite a bit when I play too so coated strings are always a plus.

                All in all I think it depends what you want out of your guitar and what guitar you throw these on. Great in some instances and highly disappointing in others. I don't see a need to purchase them again and I certainly have'nt been "converted". Sticking with elixers for now.

                Cheers.

                  I love the tone that i get from these strings. They feel good under my fingers & they're very flexible.

                  Not worth the price

                  These just aren't worth the price, IMO. I can get a set of 10 d'addarios for 3x the price of this 1 set of cobalts. That sets the standard pretty darn high IMO, and these strings are just... strings really. I noticed a little more of a brighter tone, and they do feel really nice, but I just didn't notice enough differences to justify the price.

                  Not to mention they break just as fast as every other ernie ball I've ever had. Thinking about switching to D'Addarios.

                  You would think that these strings would be major step up from the other eb strings but honestly they are average strings. They have really good tone out the box but they rust really fast dont stay n tune good at all and are pretty expensive. I love eb strings and I was not happy at all with them. I like the regular and titanium better than these. Remember slash and john get paid to say those nice things about them. They add a little tonal difference that enhances your tone for a little while thats about it.
