Medium Jazz strings for electric guitar. Pure nickel Helix strings marry the ultimate in longevity and sustain with warm tone and pristine clarity. Pure Nickel strings are easier on the frets and gentler to the touch, creating less distortion for clearly distinguished notes within chords and high speed runs. The Hyper-Elliptical compressed winding process allows for an increased number of wraps across the length of the string without altering its diameter, resulting in fuller tone, incredible sustain, amazing output, and an increased life span. Made of 8% nickel-plated steel, wrapped over tinned mandolin wire hex-core. Features set of six strings. String size: .012 / .016 / .024 / .032 / .042 / .052.
