The Ernie Ball 2153 Earthwood Phosphor Bronze strings for twelve-string acoustic guitars are made with a winding composed of 92% copper, 7.7% tin, and 0.3% phosphorus, which guarantees a clear and bell-like sound as well as plenty of volume and excellent durability. With gauges of .009/.009, .012/.012, .020w/.009, .026/.012, .036/.020p, and .046/.026, these strings produce the typical deep, shimmering sound which makes a twelve-string acoustic guitar as fascinating as it is unique. In addition, the 2153 Earthwood Phosphor Bronze string set offers impressively high tuning stability, which is particularly important for twelve-string instruments.
