Ernie Ball Not Even Slinky Nickel Wound Electric Guitar Strings (12-56)

A heavy nickel-wound electric guitar string set gauged 12-56 for high tension and a thick tone. The wound strings are nickel-plated steel wrapped around a tin-plated hex-shaped steel core, and the plain strings are tempered tin-plated high-carbon steel. The gauge is popular for down-tuned and drop tunings.
