A set of 6 tuners with pin mounts and screw-in bushings to fit Taylor guitars. These are a great choice to replace broken tuners, or to change the color, on 300+ series. With their 18:1 gear ratio, they would also be an excellent upgrade to the original tuners on 100/200 series instruments. Professional installation is strongly recommended. Improper installation may result in damage to the product and/or instrument.
