D'Addario EJ17 Phosphor Bronze 13-56 Medium Acoustic Guitar Strings

D'Addario Phosphor Bronze Acoustic Guitar strings are acclaimed worldwide for their great, long-lasting tone. Phosphor Bronze was introduced to string making by D'Addario in 1974 and has become synonymous with warm acoustic tone.

Phosphor bronze strings are generally made of 92% copper and 8% tin. The added tin improves the sustain of the strings as well as helps them last longer than bronze or brass strings.
