Lots of strings sound great — for a day or two that is! Let's face it, replacing strings (especially strings you just bought) totally sucks! With Elixir Acoustic Nanoweb strings, you get the tone you want and keep it for months after conventional strings wuss out. The secret is the ultra-thin polymer coating Elixir covers their strings with. It keeps the oils on your hands and other nastiness off of your strings so they don't corrode.
