Ernie Ball 2736 Cobalt Regular Slinky Bass Strings for 5-string bass are round-wound for maximum clarity and serious punch. The Cobalt Regular Slinky 5-String set 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 Bass Strings are the new standard! Bigger, better tone, sustain and volume. Finally a real innovation with strings." - Randy Jackson
"I can't believe how much low end I get out of Ernie Ball Cobalt Bass Strings. Also, the high end is super crisp, seemingly with more definition. Unbelievable." - Dave Larue

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: 45-65-80-100-130.

First and Last Time

By Jorge Reygadas

from Los Angeles, CA

I was looking for Elixir Strings and they didn't have in stock. Since I was in a rush and urge to get strings, the guy at the strings recommended the Cobalt by Ernie Ball as "durable" strings. WRONG. They lasted exactly 1 month and they are absolutely useless. It's the first time I have strings lasting so little. Even the regular Slinky last longer that these ones.

Best strings I've used so far...

By Kenneth Lyon

from Lake Jackson, TX

I tried out this set first out of curiosity, and they are awesome. I've used them in multiple tunings from Standard B, Drop A, Drop A#, and drop G#. Of course it was a little floppy on G#, but I managed. As of now I am using drop A, and they stay in tune, tension is right, they are easy and smooth on your fingers, and they are superb when recording. I got the tone that I always wanted with this set of strings, punchy low B, growly, throaty, they are loud, and brings your instrument a whole new life \m/ >.< \m/

If there was a no star I would have used that.

By john Sabados

Got them on my Bass, was in the process of tuning. got to C# on the D string when it let go at the bridge. Loved how they sounded, Loved how they felt. Not impressed with the quality.

Great sound but thats it!

By dillon young

from Owasso

I put these on my Ibanez SR505, they sounded great but i switch off playing at my church with our other bass player so I play and practice preety often. When I put them on they gave such great low rumbling tone and sustained well but after just a little while they lost there sustainability and on some higher notes it just fades away really fast. On some notes it even just keeps climbing and climbing in volume which is really annoying when your playing a slower and quieter song, they are even rusting now (they said they are suppose to resist moisture better). All i'm saying is that i'm done with these and wouldn't recommend them.

They Play Great For Me

By Gary Deardurff

from South Bend

When picking out new strings for my Traben Torrent 5 string I read these other reviews and almost did not buy them. I had a discussion with my Guitar Center Rep Steve and he talked me into trying them. I am glad I bought them. Set my bass and amp straight up and let their natural tone amaze me. I have not had any problems with these strings and the tone is great. Feel of the strings on my fingers is smooth and easy since I had my Steve adjust everything down as far as it can be adjusted. No buzz, just plain ease of playing with my slightly arthritic hands. In my opinion this is one purchase you should try and be pleasantly surprised with the playability of these strings. A+ in my opinion.. FuzzyB.

Awesome, but we need more different gauges.


from Lake Jackson/Houston, TX

I got two sets of this strings for my 5-string basses. One is set on standard tuning (BEADG) or sometimes on drop A (AEADG), and my second 5-string is set on drop A# (A#,F,A#,D#,G#) for my current band. They are loud like EB claims, they are smooth to the touch, and they have a sharp attack. I wish they had more options on gauges, but it is what it is at the moment. I will keep getting this strings because I like the tone, feel, and durability of them. They have gone through two sweaty rehearsals. and they still sound fresh.

Not bad

By Scott Horr

from Auburn, NE

I think the clarity of each string is excellent in standard tuning and drop d. But when I try to tune lower it sounds like the strings are too close to the frets and I couldn't get over that buzzing sound. I tried raising the strings and it still didn't seem to help. So overall I think they sound pretty good and if you know how to correctly intonate your bass you might be able to play these strings at lower tuning.

from PA

The best sound I have ever had or found in a string! But after 1 show and 2 practices. The D string broke when I was tuning 1/2 step down! Only had them on for 2 weeks. I my try another set just to see if it was a one time bad deal.
