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

The String That Defined Acoustic Tone

D'Addario invented Phosphor Bronze acoustic guitar strings in 1974, and they remain the world's most played acoustic string for good reason. Precision wound with phosphor bronze wrap wire over a high-carbon steel hex core, the EJ17 Medium (13-56) delivers maximum volume and projection — the go-to choice for players who want their acoustic to cut through and resonate fully.

The medium gauge provides more tension and resistance than lighter sets, rewarding a confident playing style with richer tone, stronger fundamental response, and the warm, bright balance that phosphor bronze is renowned for. Long-lasting and corrosion resistant, they hold their tone well between string changes.

String gauges: .013 .017 .026 .035 .045 .056
