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 seem 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.

Great Tool!

I had a Yamaha electric that was missing the nut so I didn't even have a starting template. The spacing rule made the very odd ball-sized guitar nut job painless. Thanks!

String Spacing Ruler

A good item when slotting necks, but you need to have the neck nut size that this rule is set up for. Did no good for me this time around but I know it will in the future.

With the stewmac string spacing rule, you have peace of mind that the guesswork has been removed. A guitar nut has multiple vital tasks to perform so this must be accurate, kit as cool as this is absolutely necessary, i was pleasantly surprised at how close my own measurements were to the perfect spacing, but i feel confident now that a miss is as good as a mile,this rule is a direct hit. Now i dont have to shoot in the dark, when something is not right ,,,its wrong, this rule is right as rain. This photograph shows the slight innaccuracy in my old item, and the replacement compensated nut ready for cutting and fitting to my '79 strat.
