Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings are a perfect match for those who like chunky rhythms for rock and roll or blues. Power Slinkys have long been favored by Slash, Metallica and Kenny Wayne Shepherd due to the thicker gauge combination providing a slightly more powerful tone. 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.

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: 11-14-18-28-38-48.

I bought this pack and a pack of Hybrids at GC a couple months ago. To be honest, they aren't bad, BUT all this hype that I heard about them versus how good they REALLY are, is to me just no more than gossip. First off, I do not notice any corrosion/wear differences compared to the Titanium series, actually they seem to dull out faster in my opinion. Second, while they DO increase the maximum output for your guitar, the tone is not all that's cracked up to be. It sounds way darker than what i've been used to, with brightness showing only in the higher tunings. Third, the tuning you choose will determine how well these sound. Standard, D, and C# are basically what these are made for (the Power pack is best for Drop C). Anything lower, regardless of string thickness, and it sounds like a floppy, crackly mess. Seriously, I put these on my Ibanez RG5EXFM1, and i've been using Dunlop and Titanium Slinkys for years, and these strings just made it sound like.....ugh i can't even say it without getting upset. Fourth, the will in fact (even on Bolt On Necks) give out AMAZING sustain! I played a palm muted open chord and the sustain lasted effectively 26 seconds. Bottom line, don't buy into the hype until you try them out and hear for yourself. I'm not saying they're bad, they're just limited in ability.

Just slapped a set of the .011-.048's on my Fender Telecaster. I usually put D'addario nickel wound .011-.049's on it. I tune in standard for the most part on my 6 strings with some occasional drop d stuff. The strings... I'm not overly impressed with them. They do have a lot more presence but i'm not seeing the low end like some other people are. They make my ash body Telecaster sound more twangy like alder where i like the warm sound i get from the ash body in conjunction with my D'addarios. The cleans are nice. It sounds very crisp and glassy but i'm missing the warmth and low end i'm used to. Tried changing the EQ but still didn't do it. Dirty it does maintain clarity. You can play big chords with complex voicings and still hear every note even through a lot of gain. EVEN on the neck pickup it does not get muddy. This, to me, is the best thing about these strings. But my d'addarios still had hotter harmonics which surprised me. I don't care for the feel that much either. The wound strings feel kind of abrasive like an acoustic guitar string and the plain strings have an almost brittle feel to them. bending is smooth against the fret , however. That's what i found for myself about these strings. I have a pack of .010's that i'm going to put on my Carvin when it's due but if i get the same results... back to D'addarios

I Would not buy these again....

By 

from Chillicothe,IL

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

I bought these strings after I replaced a volume pot on my Fender Squier Strat, the cobalt power slinkys lose that warm tone that the nickel wound power slinkys have and replace it with a "tinny/metallish" ringing. I personally dislike the sound, but if you're into a more metallic sound from your strings, then these strings are for you.

using in floyd rose trem

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

You have to use a gauge fit for the Floyd rose. Not even Slinky and skinny top heavy bottoms are ideal for the Floyd. Even a set of standard cobalts work fine .

Fantastic Tone

By 

from Temecula, CA

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

I heard some great stuff about these strings so I decided to give them a try. I threw them onto my ESP with D-Activators and they sound amazing. Huge amounts of sustain and harmonics fly out of the guitar like a bat out of hell. I couldn't be more pleased with the sound and feel of these strings they definitely lived up to their hype for me. I don't see myself buying any other kind of string for a long time after playing these.

Not for trem bridges...

By 

from Memphis, TN

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

I REALLY wanted to give these strings a better review. I mean, they sound FANTASTIC and they feel so much better. I noticed the difference right away with my Les Paul, buuuut....I put them on my Ibanez RG with a Floyd Rose (Yes, Floyd Rose, not an Edge), and with each set, the A string kept breaking. I know it's not the bridge because this doesn't happen with other strings, and I know I didn't get a bad set because this happened with about 6 sets. The last one caused the string block to fly out and it's now missing, leaving my RG unplayable. I'm sixteen years old, and have the budget of a sixteen year old, I can't afford to replace strings or parts all the time. In the end, they're great if you have a hardtail guitar, but not if you have a Floyd or any kind of locking vibrato. :/

Best strings I've had

By 

from Warren, Michigan

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

i bought these strings the other day to replace my DR neons. I read reviews from other people with neons saying these strings are even better so i put these on my guitar, these strings give off GREAT sound and high frequency, for example, i play Rammstein music and these strings make it sound super powerful and clear. I HIGHLY recommend these strings.

Great string replacements

By 

from Brooklyn, NY

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

I uninstalled my rotosound strings on my Gibson Les Paul guitar. What a difference in sound and feel of this string set can make? it is like OMG!!! It sounded great on my tube Fender amp on the clean sound. It feels like I could play faster because of the low action. I haven't tried my other amps yet and not even with the distortion. I am sure that it will sound great.

Better bottom end.

By 

from toledo ohio

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

Put the Slinky's on my number one strat, and it is now a Tone Monster. Looks like its time to upgrade the back-ups, as well. Great tone all the way up and down the board.

Believe me they actually sound better.

By 

from GR, NJ.

Comments about Ernie Ball 2720 Cobalt Power Slinky Electric Guitar Strings:

I was tentative at first of course, $10 is pretty expensive for a pack of strings. However, there is a noticable positive diference in the tone when you plug in. The sound is pure and the tonal clarity is unbelievable. Incredibly rich tone just from a pack of strings. I plau blues, and classic rock, perfect sound for both (and probably all) genres. I was never really an ernie ball player user until I used these, now I'm addicted. Definitely worth the $10. Give 'em a shot.
