I found these strings sounded awesome (first tried on with a new bridge so when comparing with the nickel strings I'm not exactly comparing like with like)! however after a week or two the strings still looked awesome (as in not covered in grime like my nickel 1s did) but sounded VERY dead! need to go back to nickel to really see which I prefer!

Everything they say about cobalt is true, if you move to 11s from 9s as I did you have to adjust the tremolo springs to get the bridge to stay down, but they sound great and yes they do take it out on your fingers, but they're worth it.

a little too bright and high output for classic rock/blues good for metal 18 Mar 2012
By Bryan Harvey - Published on Amazon.com
Okay... just strung these up and ran them through three different amps and about 25 different pedals (metal, overdrive, echo, reverb, fuzz, etc). So keep in mind that they haven't broken in yet as I do this review. But I do feel confident in what I report here.

They are not as nice in full warm tone as the pure nickels. On the high gain metal muff, fullbore, guytone metal monster, swollen pickle, and big muff they sound really nice.... a lot of harmonics and output captured. For that 5 stars easy. I don't think they are very versatile though below the metal shredders threshold. Other's may feel differently I am sure. Then again, Ernie Ball even states they are very bight high output. So you are getting what they say.

However, for a warm bluesy tone I couldn't get anywhere close to my sound like I can with the pure nickels. For that 1.5 star. Average to 3 I guess... :). Forget about the nickel wound steel all together (those are really lame). Either pure nickel or these depending on your style at the moment. For shredding go cobalt... for warm/woman tone go PURE nickels (that's PURE folks!!). I also really like the d'addario pures.

Also, these really did let full chords ring out on a heavy metal channel. Hope this helps.

Best so far 3 Jun 2014
By Alexdev - Published on Amazon.com

I'm using 11-48 set on PRS Hollowbody ii.

These are the best strings I've played so far. And I tried many - other EBs, Elixirs, Daddario, DR, GHS, Thomastik etc. etc. Before I tried Cobalts my favorite strings were Cleartones. Cobalts are like better version of Cleartones - richer sound, more balanced and much better feel.

Pleasantly Surprised! 11 May 2012
By Bradley - Published on Amazon.com

When I first installed these strings I wasn't too impressed. They felt different under my fingers and the sound was much more tinny than I'm used to. However, after a month and a half of playing, I really do love these strings. I got used to the feel, the tinny sound mellowed out a little, and man do they stay in tune!

Cobalt strings aren't as warm as traditional nickle strings but if you play hard rock or metal I find the gain to be more articulate. Solo's pierce through the mix without becoming too shrill and muted playing has better voicing, in my opinion. They're also super fast. I mentioned earlier that they feel different, and they do. It's not necessarily a bad different it's just slicker and not as coiled feeling. Hard to describe, but if you're used to playing nickle you'll notice the difference.

Honestly, my favorite thing about these strings is their ability to stay in tune. I went on vacation for a week, came back, picked up the guitar, expecting to have to tune it, and every single note was dead on. As they age, you'll have to make a few minor tuning tweaks but its nowhere near as frequent as nickle.

These really are a good set of strings. If you try them just make sure to give them time. They get better with wear.
Great for non-standard tuning 22 Sep 2014
By Nicholas Anderson - Published on Amazon.com
Verified Purchase
I started doing a lot of playing in drop D and drop E tuning and found that the strings I had were giving me way too much play. Getting these thicker strings eliminated almost all of the problems I was experiencing. The Cobalt strings seem to last a lot longer before they start going out of tune and losing tone quality, so to me it is well worth the extra cost of getting cobalt strings because I find myself changing them less often. These strings might be a little thick for you if you do all your playing in standard E tuning, but if you drop your tuning down at all, I would highly recommend these.
Sound great, high output and stable tuning 23 Aug 2014
By Michael F. - Published on Amazon.com
Verified Purchase
Sound great, high output and stable tuning, but if you break a string you're stuck with buying a whole new set. They sound different enough that it'd be noticeable if you had to replace one (say a broken hi e) midset. Switched back to my old brand right away (before my next gig). If they ever offer the option of buying single strings I'll probably switch back.
