D'Addario Phosphor Bronze Acoustic Guitar Strings - 12-String 12-52

Gauges: 12/12-16/16-25/10-32/14-42/20-52/30

D’Addario EJ39 Phosphor Bronze 12-string acoustic guitar strings deliver the warm, balanced tone that has defined acoustic sound for decades. First introduced by D’Addario in 1974, phosphor bronze has become the industry standard thanks to its rich tonal balance, clarity, and versatility across musical styles.

A medium-gauge 12-string set designed for bold projection, fuller resonance, and strong acoustic presence.

Precision wound with phosphor bronze wrap wire over a hexagonal high-carbon steel core, EJ39 strings provide excellent tuning stability and consistent intonation. The 12-52 medium gauge produces increased tension compared to lighter sets, resulting in a more powerful, resonant voice ideal for players seeking maximum depth and projection from a 12-string acoustic.

Each set is packaged in a corrosion-resistant recyclable VCI bag and includes a Players Circle code for rewards registration.
