eferred 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. 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.
