D'Addario EJ41 Extra Light Phosphor bronze

EJ41, D'Addario's lightest gauge 12-string acoustic guitar set provides easy playability while retaining adequate tone and projection for most playing situations.
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.
