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.
Behind every set of D'Addario strings are over three centuries of fine craftsmanship. The D'Addario family tradition began in the tiny town of Salle, Italy in 1680 where they made assorted instrument strings for over two hundred years before relocating to New York in 1905. As the modern string making industry began to develop, the D'Addario family emerged as innovators by designing the winding machine most string makers still use today. And while their techniques have modernized, the pride that goes into each set of strings dates back to the D'Addario family's earliest roots.
EJ17 is a medium Phosphor Bronze set that offers heavier gauges for increased volume and projection. The increased tension makes them ideal for drop or altered tunings as well. Since D'Addario introduced Phosphor Bronze guitar strings in 1974, they have been synonymous with warm and well-balanced acoustic tone.
