D’Addario’s lightest gauge of 85/15 acoustic strings, EZ890s are ideal for beginners or players who prefer a softer tone and easy bending. 85/15 Bronze combines the brilliance of 80/20 bronze with the longer life characteristics of Phosphor Bronze. The 85/15 Bronze wrap wire is precision wound onto a carefully drawn, hexagonally shaped high carbon steel core, resulting in long lasting, bright sounding tone with excellent intonation.
