The Original String

Pioneered in 1974 and still revered today, Phosphor Bronze has become synonymous with warm, well-balanced acoustic tone. D'Addario Phosphor Bronze strings are precision wound with corrosion-resistant phosphor bronze onto a carefully drawn, hexagonally shaped, high carbon steel core. The result is long-lasting, bright sounding tone with excellent intonation.

"I use Phosphor Bronze Med EJ17 strings on my acoustic guitar. Years ago a musician friend recommend them to me because I squeeze heavy when I'm playing and I've been using them ever since. I just love the quality and feel of the medium strings. I also like to leave my strings on for a long time and these strings last."
