Ernie Ball Coated Slinky Strings combine the latest technological advancements in string manufacturing. All wound strings are treated with a micro-thin layer of enamel that prevents decay and corrosion up to five times more than uncoated sets. In addition to treating the wound strings, each plain string features a rust-resistant plating along with a patented reinforcement winding of titanium wire. Titanium's inherent strength prevents string breakage, string slippage, and is proven to keep your guitar strings in tune better than conventional plain strings. Ernie Ball Coated Slinky guitar strings maintain the feel and sound of uncoated sets, combining the added protection with the vibrant tone Ernie Ball customers have relied on for over 50 years.
