This set of GHS strings has a crisp, warm sound. The light string tension provides the player with an easier action or playability while producing good volume. We have been a dealer for over 30 years and do a healthy volume. This means the strings we sell are always factory fresh. I string my Guitar Works, Inc. mandolins with this set. They seem to be perfect for most of our customer’s playing style and abilities. The gauges are .10 .15 .24 .36 For those of you not familiar with GHS it is an American String maker located in Battle Creek Michigan. For over 45 years some 100 experienced workers have produced the worlds finest strings in house, on their own machines there in Battle Creek.
