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.

First: The string spacing rule is easy to use and is a very helpful tool...it takes a lot of speculation out of the mix when laying out and cutting nut slots. Most Important: I received a rule that had been shipped in a questionable fashion and resulted in the rule being bent. I contacted Customer Service and they very helpful ande replaced the rule. So, I will rated SM an excellent PLUS on customer service and customer satisfaction!!!!

An excellent tool.
I have experienced Gibson Les Paul guitars with first string
sliding off fretboard much too easily.

It has always been my opinion that the first string is spaced incorrectly
on Gibson Les Paul Standard guitars.

I use the spacing rule to check - and then compensate strings 1 and 2 appropriately.

Thanks Stewart-MacDonald.

The Perfect Tool

Trying to save money, I have made cardboard and plastic versions of this over the years, but they never had the accuracy of this spacing ruler. Do yourself a favor. Buy this very unique and accurate tool. I expect mine to last a lifetime, and assure perfect notch spacing every time.
