Product DescriptionErnie Ball welcomes two new popular gauge combinations to its world famous Slinky line of electric guitars strings. Burly and ultra Slinky guitar sets feature the same great bright and balanced tone that Slinkys are known for, in new never-before-offered gauge combinations. Ultra Slinky's combines the popular regular Slinky and power Slinky strings into one set featuring the lighter playability of the regular Slinky with the heavier low-end tone of the power Slinky set. This combination is perfect for lead players who love to bend without losing fullness or tension for rhythm and chords. 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. Both sets feature 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.From the ManufacturerErnie Ball welcomes two new popular gauge combinations to its world famous Slinky line of electric guitars strings.
