With the development of the XS series, optimization of the string's lifespan has taken top priority.
Thanks to the technical advances in the field of protective coating, the D'Addario XSE0942 XS 09-42 guitar strings astound with longevity never before experienced from a guitar string. Each string undergoes a polymer treatment and is coated with an ultra-fine film to protect against corrosion and raise the strings' lifespan to that of the immortal Rock Gods.These features, however, do not rob the strings' of their excellent sound or pleasant sensation while playing.
Through the marvel of modern technology, the D'Addario XSE0942 XS 09-42 guitar strings were born and they will stick around for longer than any other guitar strings could even dare to dream.
