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.

String Spacing Rule

This is a great tool if you are cutting nuts from blanks. This is especially true on a bass where even spacing makes the low strings feel crowded if not deferentially spaced. Don't know why I didn't buy it years ago. I used to "figure out" the differential spacing, now it's a snap.

no brainer

I make everything! I shape the body and neck, I build the bridge and of course the nut...everything. this little ruler saves time!! Guitars, basses, whatever your making you set it on it gives you the perfect spacing every time.

Mess up proof.

This makes marking the nut less cumbersome. This int cumbersome at all really. It sucks when your ruler moves. Of course this results in better accuracy, and faster completion of the job.Time is money.

Convienient tool to have in your kit

I always just spaced strings using a standard steel rule. On a whim I bought this gauge and am glad I did. Makes accurate string spacing on nuts and bridges so much faster and easier.

String Spacing Rule

This is one of those tools that you wonder why you'd waited so long to purchase it. Fear no string spacing when using this tool. Fast, easy to use and understand and the 5 star results make it darn near indespensible. If lost or damaged I'd replace it.
