Cobalt slinkys bass strings

These strings are the very best strings I have ever used. I have used Elixiers, Daddarios, DR, Rotosound, regular Ernie Balls, and they all lost their tone with in a week or so, and their sustain . Some were muddy others rubbery. But these strings have great sustain, and brightness for months, I have been playing these sets for about three and a half months ,and they still have good sustain, growl, brightness. These strings also stay in tune very well, and I like them so much that I put them on all my basses. These strings are also louder than all other strings, and stiffer too which gives me more control. These strings cost more than others but I'm pretty sure a lot of you bass players will like them. I have no idea if their good for slap, but I know for sure they are great for classic rock, alternative, and all metal types. Worth a try.

Excellent!

I too was interested in the hype and was looking for brightness and clarity. I have used GHS Bass Boomers and Super Steels (Super Steels are great btw). I've also used Tomastik Infeld's and others. The Tomastik's are unique to me, in that they have a great warmth and kind "perfect" bass sound to them. Not overly bright, but clear. They did feel a bit "heavy" to me, like the gauge was bigger than I was used to or something.The Cobalt Slinkys rock. Period. They are louder, brighter and have a distinct sound in my opinion. It's like you're getting everything you possibly can out of your guitar, BAM!For instance, after putting a new set on my Musicman Stingray HH 4-string, I noticed that I had cut the D string a bit too long and it was binding up on the post, making that string a little harder to tune. So, after a few weeks I decided to take it off and cut it a tad shorter. Of course I cut it too short and ruined it and was forced to replace the string with whatever I could find for a practice session. I chose a set of regular Ernie Ball Slinkys to purposely go cheap until I could replace it with another Cobalt. I wish I had only bought a single string now... I replaced just the missing D string. (and yes, everyone knows that Ernie Ball Slinkys are about the cheapest quality strings you can buy)What a difference. Dull, boring and lifeless. lol. Huge difference in volume and not nearly as clear sounding as the two week old, many practice sessions, Cobalts. All my pop was gone in my D string. It sounded like an old rubbery string you find on some old dusty guitar sitting in the corner of someone's house, and it was brand new, lol. I was instantly convinced of the Cobalts superiority. The jury is still out in my search for a favorite bass string, but the Cobalts are impressive to say the least.If you're looking for clarity and power, they are certainly worth a try!

Excellent Strings

String selection is highly personal and subjective. While I think most brands sound great when their new, such as Fenders and D'addario, most of them seem to lose tone after a couple of weeks. Prior to the Cobalts I used Elixirs, which did not initially sound as good, but kept their tone for a longer period. These Cobalts have more mid-range bite and appear to be louder than most of the other strings I've used. I like them when using a pick or my fingers. I don't do much slapping, and I doubt they would be suitable for that style. No problems with breakage or loss of tone.

These strings suck!

For years I have used Fender, Dadarrio, or Dean Markley bass strings. I normally do not use Ernie Ball strings. The quality always seemed to be cheap. Turns out I was correct. I was lured in by the Cobalt hype and so I forked over the money to try a pair of my first Ernie Ball strings. Within minutes of having the strings on my bass the A string broke. I was not even playing that aggresive to begin with. I am very dissapointed with the quality of these strings. Thus I will not ever buy another set of Ernie Ball strings again nor will I recommend these to anyone else.
