Ernie Ball Slinky electric guitar strings have been the favorite of legendary artists like Eric Clapton, The Rolling Stones, Jimmy Page, Slash, Green Day and more. Slinky gauge combinations were pioneered by our founder Ernie Ball over 50 years ago, helping shape the sound of rock n roll. Nickel Wound Slinky strings consist of nickel plated steel wrapped around a tin plated high carbon steel core for a balanced tone that compliments all guitar types and playing styles.
