Nut Slotting Gauge

A revolution in guitar setup! Precisely measures string heights, so you can cut accurate nut slots for consistent playability.

This device that will revolutionize the way you set up a guitar.
The Nut Slotting Gauge quickly and precisely measures string heights over the first fret. When filing nut slot depths, you see your results more accurately than ever before. No more guesswork or "eyeballing" the string heights, and no more searching for elusive combinations of feeler gauges. You can custom-tailor the playability with consistent, repeatable results.

At last! A precision tool for establishing string heights!


The Nut Slotting Gauge was designed by Don MacRostie here in our R & D shop. It features an easy to read dial indicator with adjustable zero point, and it's super accurate to .001". The machined brass base fits over the strings to rest on the fingerboard, and it works with most acoustic and electric guitars, mandolins and banjos. A larger brass base is machined to fit bass string spacings. Both have gently arched bottoms to follow most any fretboard radius. Instructions are included.

The Nut Slotting Gauge is included in this money-saving set: Nut Slotting Gauge and Neck Relief Gauge Set

Nut Slotting Gauge

By
(Customer's Reviews)


This is an excellent tool, worth the money if you have several instruments.

I have checked and adjusted about a dozen guitars since receiving the gauge. Drop the gauge on and in a second you can see why its always been tough to play those bar chords! I caution people to be careful though, those thinners strings drop quickly if you are heavy handed with the file! I overcooked a couple of fine strings because I didn't have the right width file. I was measuring and filing not realizing I was filing a narrow groove and the string hung up and then suddenly drop (whoops). Have ordered more files from Stew Mac, so this wonÆt happen again! Its a great tool, my only suggestion for improvement would be a dial that was calibrated backwards as you are always pressing down and therefore deducting from the starting datum point.

The most precise way to adjust strings

By

I've adjusted strings with feeler gauges and guesswork before but this takes all the guesswork out of it. It rests on the string. You zero it. You press down and you have the distance. It couldn't be easier. They do seem to have designed it to work the other way around, which would mean you'd have to zero it while you hold down the string and the let up to read it, but it's not that hard to read backwards and easier to set to zero while not having to hold it down as well.

I had always struggled with setting the action at the nut. After using this tool the first time, I kicked myself for not getting it sooner. Makes the job faster, easier and gets rid of the guesswork.

Nut Slotting Gauge

An excellent idea, but the dial on mine does not reliably come to rest at the same place. As a result, I take many measurements and I assume the average is within .005" of the actual height. If the dial were more reliable, it would be great.

Best Action Yet

By
(Customer's Reviews)


I used the nut slotting gauge on my latest guitar Project. There is no guessing or messing around with feeler gauges trying to get the action at the nut just right, you know within seconds exactly the height of the string over the first fret. I would not do another nut without it.

Great tool!

By

Thanks for developing such a great tool for adjusting string height at the nut. Makes the job quick, accurate and easy! Because the dial actually measures on a countdown rather than count up basis, I zero the dial while the string is pressed to the fret so during the adjustment process, I just rest it on the string (without depressing) to see the height without having to depress the string or do the subtraction to determine the measurement. Thanks again. Jim

Fantastic ... small, simple, accurate. Like a little piece of functional art. I want a second one for my car dashboard. Many thanks to Don MacRostie.
