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.

String Spacing Made Easy !!

By

Verified Buyer


Had always been generally not real crazy about nut making and figuring out string spacing. Usually this job occurs at the end of the assembly process and my patience can run thin because of my anticipation of what the instrument is going to sound like. In the past , this reoccurring mind set had always made be dread the making of the nut. I finally bought this string spacing rule about six months ago and have used it on 4-5 guitars and I MUST TELL YOU MY STRING SPACING WORRIES ARE OVER. THIS THING WORKS GREAT!!! I HIGHLY RECOMMEND IT!!!
Sincerely,
Richard Samuelson

It's awesome, I use it to make my guitar (And other instrument) plans and that help me very quickly!

There is a other technique to make the separation of the strings with compensation, but it's really long...
I love it!

This is a Great Tool!!!

I needed to take the guess work out of making a nut, the String Spacing Rule works Great for that. It brings up the quality of my work to where I want it to be. If you don't have one of them, GET ONE, it's worth the money invested!! Take the time to understand how this rule can help you in your shop...it's worth it. Practice on a few "Test Nuts", I used wood/cheep plastic for this, you'll get the idea of how it works without messing up a good bone nut. In the end, if you have a Happy client, they will come back to you for more work.

This is a must for every guitarist

Every guitarist should be able to do something easy as changing their bone nut since almost every guitars come with cheap ones. And this thing just make it easy to figure out where to cut the nut, so that everyone can do it now! I don't even understand why other brands aren't doing those..... go figure...

Takes the guess work out

I received a '53 Guild from a friend that was torn apart and came with a new nut with no slots. This tool took the guess work out of the very narrow nut and made short work of that aspect of the project. Excellent, quality tool.

Love it, and one of the Stewmac MUST HAVE TOOLS!

You set up your 6 strings or 7, or for 12 you do 6 and the two double plain strings, get a good spacing for your octave strings, then lay over and do your G, D,A, and E octave strings, off your initial setup. Regular guitars and basses are pretty self explanatory. Re-entrant instruments like the Charango can be laid out with this too, using the same techniques as the 12 string with a few extra steps, but it will do the trick, and do it very well.

I bought this after I had to replace the nut on an older Alverez acoustic. I wish I had it before I did the work. I may still use it on that guitar if I don't like the nut I just installed.
