Allparts String Spacing Rule for Guitar and Bass

Model Overview

If you're cutting nuts for guitars, mandolins, basses, or any stringed instrument, this tool belongs on your bench. It takes the guesswork out of string layout—no need for calipers, calculators, or ruler gymnastics. Just fast, accurate, and proportional string spacing every time.

Made from flexible stainless steel, it conforms effortlessly to both flat and radiused nuts. Thanks to precise laser-etched markings, it's easy to read and delivers consistent, professional results. This tool spaces the gaps between strings evenly (not just the centers), ensuring better playability and a more balanced feel.

Simple, repeatable process:

• Mark the two outer string positions on your blank
• Line up the template with the correct number of strings
• Match the etched spacing marks to your outer string marks
• Mark the centers and you're ready to cut

Perfect for both single and double-course setups. If you’re doing multiples, just highlight the correct spacing marks with a pen for quick repeat use.

A true time-saver—and a precision upgrade for any luthier or tech.
