For players who want bold, full-bodied tone with powerful projection, the D’Addario XS Phosphor Bronze 13-56 Medium set delivers. These strings are built with precision NY Steel cores, advanced Fusion Twist ends, and D’Addario’s premium XS coating — providing the perfect balance of strength, stability, and long-lasting tone.

The 13-56 gauge offers greater tension for rich lows, strong mids, and dynamic volume, ideal for flatpickers and strummers who need presence and punch. Despite their strength, the XS coating keeps them smooth to the touch and resistant to grime or sweat. Expect consistent tuning, longer life, and a refined, expressive tone that elevates every performance. Gauges: E4 .013, B3 .017, G3 .026, D3 .035, A2 .045, E2 .056.
