D'Addario EZ920 American Bronze acoustic guitar strings, here in medium light gauge 12-54, are made from 85/15 Bronze which gives a stunning bright, crisp sound but with the low end, projection and long lasting qualities of Phosphor Bronze.
These round wounds are precision wound for maximum consistency and excellent intonation. In a medium light gauge these are the ideal size for a bit of everything.
From strumming, to finger picking to down tuning and playing with a slide, it's a very versatile gauge.
The individual thicknesses are: .012, .016, .025, .034, .044, .054.
