Bass players will get nothing less than what they would expect from a Hartke product: Reliability, consistency, and ultra-fast transient response for a brighter, richer, more defined tone. The Hartke Bass Strings come in 12 configurations, including 4 and 5-string sets of XLight, Light, and Medium, available in single and 3-packs. They are long scale, nickel-wound, hex-core strings, with color-coded beads for easy identification.
