Ultra-thin film coating
D'Addario has gone to great lengths to ensure every string in every pack of XS Phosphor Bronze stays true to the iconic D'Addario tone. The secret is a unbelievably thin coating that preserves tone, above all, but also reduces squeaks and resists fraying. This coating not only gives you longer string life, but also a comfortable feel on the fingers so you can play your best all night long.
