Improve the tone of your Bass Guitar immediately with this 42 mm wide nut for right-handed Bass guitars (a very common width for Bass Guitars). This product is made Buffalo Bone--a denser and harder material than plastic which can result in improved tone. This customizable premium nut measures 38 mm (W) x 3.5 mm (D) x 6 mm (H). The bottom style is flat as shown in the photos. To install, simply sand down the bottom of the nut to your desired string action height and fine tune the nut slots as needed. A sample of 150-grit sandpaper will also be included.
