More range, better harmonic response, thanks to the power of cobalt.
Part of the Ernie Ball Cobalt Slinky Guitar Strings Series, the 2728 Cobalt 7-String Regular Slinky Electric Guitar Strings are engineered to maximize output and clarity, and are the latest innovation in string technology. Seeking to provide guitarists and bassists with a new voice, Cobalt strings provide an extended dynamic range, incredible harmonic response, increased low end, and crisp, clear highs. Cobalt is the most magnetically active string alloy on the planet and attracts the magnets in your pickups more than any other string. Cobalt Slinkys are also soft and silky to the touch, making string bending a breeze.
