From Ernie Ball:
Ernie Ball Earthwood Silk & Steel Regular 80/20 Bronze acoustic guitar strings are made with an 80/20 bronze alloy wrap, along with a layer of silk between the wrap and steel core. The silk produces a more mellow sound and makes the string feel more comfortable while reducing finger noise. Gauges .013, .017, .026, .034, .046, .056
