Acoustic guitar bridge pins wear or sometimes break and need replacement. In this case, replacing one pin is acceptable. More commonly, our bridge pin work is for upgrades. Upgraded bridge pins can be both tonal and cosmetic upgrades. Slotted or un-slotted are both popular and there are many materials to choose from. In all cases, the bridge pins should be well fit and the strings properly seated into the bridge. These are small details that we often see overlooked on guitars.
