Try the new and improved extra slinky feel and fat tone.

Ernie Ball 2735 Cobalt Extra Slinky Electric Bass Strings are round-wound for maximum clarity and serious punch. 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 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 40-60-70-95.

        Comments about Ernie Ball 2735 Cobalt Extra Slinky Electric Bass Strings:

        They produce a higher output and they're brightness lasts noticeably longer than traditional strings. Beautiful tone, very similar to nickels in most respects but with a little low-mid boost and tightened high end. The harmonics really pop on these and the tone sits well in a band setting. You get a nice foundation without getting muddy and you cut through with articulation without being obnoxious. They're nice and smooth like nickel round wounds and have a nice even feel.

        I've been through a few sets and one problem I've had with them is that the high strings sometimes break, but I have to say it's probably due to my technique (over bending and popping heavily)and how light this particular guage is. I'll be getting a heavier set of the hybrids (45 65 85 105). This has helped when I had this problem in the past. If your a fan of nickel round wounds give them a try.
