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 strings windings hence preserving the coveted phosphor bronze tone. We here at Steilberg String Instruments are very excited about these strings. This is what a lot of people have been waiting for - ourselves included. Treat yourself.
