D’Addario Acoustic Guitar Strings XS Coated Phosphor Bronze Series

XS is breathing new life into coated strings. With its ultra-thin film coating on every wound string and unique polymer treatment on the plain steels, XS offers our highest level of protection for maximum life with an uncommonly smooth feel. XS is the most innovative coated string ever created.

"Several years ago, I posed a simple question to our team of engineers and
product designers: Can D'Addario create the world's greatest coated string, bar none?

I am proud to say our team rose to every one of these incredible challenges (and a host of others) and we're launching the new XS coated string."

- JIM D'ADDARIO, Chairman of the Board/Chief Innovation Officer of D'Addario
