Elixir Nanoweb Coated Electric Guitar Strings Custom Light .009-.046 New guitar strings sound great. They are usually bright and crisp, and the guitar delivers a punch most musicians prefer. Unfortunately, body oils, perspiration, and corrosion quickly compromise sound quality and brightness. ELIXIR Guitar Strings are perfect for all musicians who need great sound and consistent performance, plus the benefits of less squeak and faster action. Casual players or musicians who own several guitars prefer ELIXIR Guitar Strings because a guitar can sit in its case and still sound great when played occasionally. All players will enjoy the comfortable feel of the PolyWeb Coating. The development of NanoWeb Coating was initiated by musician feedback. At a mere 400 nanometers thick, NanoWeb Coating is about 30% of the thickness of PolyWeb Coating -- the original coating technology featured on Elixir Strings. Substantial innovations by Gore in fluoropolymer technology have enabled the development of this ultra-thin coating that retains the exceptionally high durability that musicians have come to expect from Elixir Strings.
