The consensus among many musicians is that phosphor bronze strings offer the most sensitive, expressive tone that brings out the very best in guitars—virtually taking them to a higher level of play.  However, that tone can be short-lived. Elixir Strings has solved this classic conundrum by applying an ultra-thin layer of NANOWEB Coating to protect the string’s windings hence preserving the coveted phosphor bronze tone. These Elixir Strings capture the sweet spot of that unique phosphor bronze tone and extend it 3-5x longer than conventional strings.
