Ernie Ball 2733 Cobalt Hybrid Slinky Bass Strings are round-wound for maximum clarity and serious punch. Featuring a combination of Super Slinky and Regular Slinky gauges, the Cobalt Hybrid Slinky 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 45-65-85-105.

    Really like the tone on these. Texture is a bit rougher than what I usually use , but definitely doable. Finding them on clearance was a great deal ! Happy camper and #sweepstake entry.

  • Yes I would buy this set of strings again

    Ernie ball hit a home run with these strings. I have used a lot of different strings over the years, including Ernie Ball Hybrid slinky. After using the new Cobalts, I am blown away. Super bright! I will never use another string.

    These strings are loud, bright and have a decent feel. They are better than standard Ernie Ball strings, but are still a little floppy on the low E string, especially if you tune down to drop D. They have a good sound for slap, but are so bright, I found myself turing the treble way down on my bass to keep them from being harsh. Because of the floppiness in the E string, I can't get the action too low without buzz. Overall, they're not bad, but not great either.

    These strings would be compatible with the Schecter MA-4.
