** Optimal For Detuning ** 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.
