D'Addario Medium 13-56 Phosphor Bronze for Acoustic Guitar (6 string set)

D'Addario's EJ17 is a medium Phosphor Bronze set for acoustic guitar that offers heavier gauges for increased volume and projection. The increased tension makes them ideal for drop or altered tunings as well. They are a bit light for dobro G tuning, but could be the right tension for some resonators. Since D'Addario introduced Phosphor Bronze guitar strings in 1974, they have been synonymous with warm and well-balanced acoustic tone.

From daddario.com "D'Addario was the first to use Phosphor Bronze in acoustic guitar strings back in 1974. Today, Phosphor Bronze is played throughout the world and considered to be the standard in acoustic strings, thanks to its beautiful sonic balance and tonal warmth. Our pioneering Phosphor Bronze acoustic guitar strings are precision wound with phosphor bronze wrap wire over a high-carbon steel core, providing tonal versatility suitable for all acoustic styles and musical genres. 13-56 Medium gauge strings provides maximum volume and projection, with more tension and resistance."
