D'Addario Medium Gauge 12-String Guiar Strings 12-52 EJ39

EJ39 is a medium top, heavy bottom Phosphor Bronze set ideal for increased volume and projection for acoustic 12-String guitars. Since D'Addario introduced Phosphor Bronze guitar strings in 1974, they have been synonymous with warm and well-balanced acoustic tone. 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.
