A set of strings designed for a modern, powerful, and detailed sound
The Ernie Ball 2720 Slinky Cobalt Power Slinky 11-48 are aimed at electric guitarists who want to gain definition without losing impact. Thanks to cobalt, the guitar responds with more presence and clarity, especially in the mids, for dense riffs, expressive solos, and an attack that immediately stands out in the mix. The 11-48 gauge provides a "power" feel: more resistance under the fingers, better stability, and a firm output that highlights both heavy chords and precise leads. The hermetic pouch packaging helps keep the strings fresh upon opening, ready to deliver their full potential from the very first chord.
