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.
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.
