D'Addario 12-54 Phosphor Bronze Acoustic Guitar String Set Medium Top/Heavy Bottom

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. This 09-45 Extra Light 12-String set is D'Addario's lightest gauge for 12-string acoustic guitar, providing easy playability while retaining adequate tone and projection for most playing situations. Designed for all makes and models of 12-string acoustic guitars, this 10-47 Light gauge set is D'Addario's most popular 12-string set, offering the ideal balance of volume, projection and comfortable playability. This 12-52 Medium 12-string set provides heavier tension, resulting in a bolder, more resonant acoustic tone with higher resistance. Ideal for aggressive fingerstyle playing, this 12-54 Medium Top/Heavy Bottom 12-string set features the playability of a medium gauge set, with the enhanced volume and projection of heavy gauge bottom strings.
