String Spacing Rule

About This Item

Get accurate string spacing without calipers, calculators or shop rulers.

Our laser-etched stainless steel String Spacing Rule quickly finds the right spacing for just about any stringed instrument. It does all the math for you: proportional slot spacing automatically compensates for string diameters, from treble to bass, so the thicker strings won't feel crowded to the player.

The problem is: if you space the strings equally, they don't feel equally spaced. The thicker bass strings seem crowded together. Each gap between strings has to be slightly different to feel right to the player. How do you calculate this? The String Spacing Rule takes care of it, for guitars, basses, mandolins, and banjos.

Fast. The String Spacing Rule is slotted so you can quickly mark the string positions onto the nut. Use a scribe instead of a pencil, and it creates extremely accurate starter grooves for your nut slotting files.

Easy to use. Mark the two outer string positions onto the nut. Slide the rule over the nut to find a set of slots that matches your two marks. Now just scribe or pencil the string positions onto the nut! No measuring, dividing or calculating — the rule does the math for you.



Accurate. The rule's slots are laser-cut in a continuous scale that wraps around both edges of the rule (our thanks to luthier Kevin Ryan for creating this tool). Proportional slot spacing subtly compensates for the diameters of the individual strings, from treble to bass, to give the right feel and playability.

Not just for nut slotting. You can use the String Spacing Rule to notch Tune-o-matic bridge saddles, to lay out bridge pin holes, and when notching archtop guitar, banjo, mandolin and violin bridges.

The String Spacing Rule is made of laser-etched flexible stainless steel that conforms to flat or arched surfaces. Instructions are included.

The String Spacing Rule is included in the Essential Nut Making Tool Kit, which has all the basic tools you'll need for shaping, string-spacing, slotting and fitting string nuts like a pro.

This tool saves me a lot of time on nut replacement jobs. It's a good quality accurate tool. Like another reviewer has already mentioned, I also have a piece of tape along the middle to allow me to mark which slots I need to use.

I love it... mostly

I have had one of these for years now and use it all the time. It is one of the few tools I own that has saved me tons of time and improved my life tremendously. I do have one complaint though -- occasionally I run across a guitar that needs a new nut with a very narrow spacing (usually because the fret ends are rounded off too much) and the spacing required is too narrow to measure with this tool. I would suggest that the next version of this was long enough to add enough slots on the wide end to fill the gap between using every other slot on the narrow end and using adjacent slots on the wide end. There is a range that exists in the real world that this tool currently doesn't cover.

I love this thing. I added a piece of tape down the middle, so I can easily mark with pencil and see the marks. This is a must for anyone working at home or in a shop.
