Manufactured to the highest standards the Phosphor Bronze strings prevent corrosion from sweat and reduce oxidisation which produces rust. The Earthwood Phosphor Bronze are played by the likes of Paul McCartney and offer a mellow sound with warm and rich overtones. This rock and blues set has a gauge of 10-52 and produce a clear sound that works well with any genre and playing style.
