These are some of our most popular bass strings!
They are flatwound, but have the sound of rounds because of the SuperBright Cobalt ribbon wrap, Cobalt underwraps and optimal hex-core to wrap ratio.
Engineered to maximize output and clarity, Ernie Ball Cobalt Slinky bass strings are the latest innovation in string technology. Seeking to provide bassists with a new voice, Cobalt strings provide an extended dynamic range, incredible harmonic response, increased low end, and crisp, clear highs. Cobalt provides a stronger magnetic relationship between pickups and strings than any other alloy previously available. Cobalt Slinkys are also soft and silky to the touch, making string bending a breeze.
