Phosphor Bronze was introduced to string making by D'Addario in 1974 and has become synonymous with warm, bright, and well balanced acoustic tone. D'Addario Phosphor Bronze strings are precision wound with corrosion resistant phosphor bronze onto a carefully drawn, hexagonally shaped, high carbon steel core. The result is long lasting, bright sounding tone with excellent intonation.

Which Includes:
EJ15: D'Addario's lightest gauge of acoustic strings, EJ15s are ideal for beginners or any player that prefers a softer tone and easy bending.

EJ16: D'Addario's most popular acoustic set, EJ16 delivers the ideal balance of volume, projection and comfortable playability.

EJ17: They offer heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming and flat-picking.

EJ18: They offer heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming and flat-picking or for down tuning.

EJ19: A D'Addario hybrid gauge, combines the medium gauge bottom strings for increased resonance and volume with light gauge top strings for more comfortable playability and single note bending. A popular choice for bluegrass pickers but suitable for many genres.

EJ26: Referred to as Custom Light, EJ26 strings are a D'Addario original hybrid gauge and a comfortable compromise for players who want the depth and projection of light gauge bottom strings, but slightly less tension on the high strings for easy bending.
