ERNIE BALL Power Slinky.

Ernie Ball Power Slinky Electric Guitar Strings are a perfect match for those who love chunky rhythms for rock and roll and blues. Power Slinkys have long been favored by Slash, Metallica and Kenny Wayne Shepherd due to the combination of a thicker gauge providing a slightly more powerful sound. The flat strings are made from a hardened, tin-plated carbon steel that produces a well-balanced sound.
