Ernie Ball Extra Slinky Cobalt Electric Bass Strings - 40-95 Gauge

4-string set for electric bass guitar from Cobalt series that features round-wound strings 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 the pickups more than any other string. The strings are precision manufactured to the highest standards and most exacting specs to assure consistency, optimum performance, and long life. Gauges: .040, .060, .070, .095.
