D’Addario EZ920 85/15 Bronze Medium Light Acoustic Guitar Strings 12-54

85/15 bronze (aka. Great American Bronze) is a lesser-known string that combines the sustain and long-life benefits of phosphor bronze with the brightness and brilliance of 80/20 bronze. The string starts with a D’Addario high-carbon steel hexagonal core which has high tensile strength, excellent intonation, and stable tuning. It is then precision machine wound with the 85/15 bronze wrap wire resulting in a long-lasting, bright and percussive string.
