Hipshot's Roller Nut for Dobro is a sure fire way to maximize your tuning stability. Conventional nuts-no matter how well lubricated- grip the strings as they slide over, causing you to go out of tune. Gives each string its own free wheeling roller which means your strings glide over- keeping you in tune.That's why it is essential to use the Roller Nut (and Grip-Lock Tuners) for installations of the DoubleShot. Made in USA.
Installation Available, but not included
