D'Addario EJ37 12-String Phosphor Bronze Acoustic Guitar Strings, Medium Top/Heavy Bottom, 12-54

EJ37, D'Addario's medium top/heavy bottom 12-String acoustic set features the playability of a medium gauge set with the enhanced volume and projection of heavy gauge bottom strings, ideal for aggressive fingerstyle playing.

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.
