Burly Slinky guitar sets feature the same great bright and balanced tone that Slinkys are known for in a new never-before-offered gauge combination. Burly Slinky strings are ideal for players who prefer a heavier set of strings for thicker sounding chords beefier low end but also require a little more tension when playing solos. This set features nickel-plated steel wrap wire around a steel plated hex core for that iconic Slinky feel and tone that players have relied on for decades.
