Engineered to maximize output and clarity, Ernie Ball Cobalt Slinky guitar strings are the one of the latest innovations 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 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. Cobalt strings have a slight blue hue, compared to other Ernie Ball electric strings. Gauges .011, .014, .018p, .028, .038, .048. Part number 2720.
