XS Phosphor Bronze strings have the longest life of any D’Addario acoustic string, thanks to the ultra-thin XS film coating.
Phosphor Bronze wrap wire provides tried-and-true D’Addario acoustic tone, with beautiful balance and warmth suitable for all musical genres.
With an NY Steel core and Fusion Twist technology, XS Phosphor Bronze offers greater break strength and unmatched tuning stability—staying in tune 131% better than standard acoustic strings.
XS coated acoustic strings are made in the USA—drawn to D'Addario's exacting specifications at their New York production facility.
