Gauges 10-13-17-26-36-46. Elixir Electric Guitar Strings are covered with an ultrathin, space age polymer tube that contacts the string on the tops of the windings only. This leaves the all-important winding-to-winding-to-core space free from the fear of the enemies of tone! No more gunk and goo. No more DNA evidence. No kidding.In addition to an ultrathin grunge-resistant tubular coating on the wound strings, Polywebs now have a revolutionary Anti-Rust plating on the plain strings to extend their life too.Elixirs are the first major innovation in guitar strings in over 40 years, and deliver what they promise: great tone and long life no matter what you put them on or how often you play.
