Nut Slotting Gauge

About This Item

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

This device 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

This gauge makes the job so much easier. I have found that pushing down on the stem works well with repeatable results.

I'm a Novice repairman, not in any way a professional repairman, that I know comes with years of experience, but this device makes it easy enough that even I can set the nut the way I want it..with more accuracy,, a lot easier than feeler guages.. Good Product

Nut Slotting Guage

By
(Customer's Reviews)


I tried to use my nut slotting gauge to file the nut slots on my Strat to the correct depth, one thing I noticed was that the accuracy was a bit out, I discovered this by using the gauge to file a string slot so that there was 0.018" clearance between the top of the first fret and the string, then I used a 0.018"-thick feeler gauge blade to check, the string clearance was actually more than the feeler gauge, as far as I knew, I was using the nut slotting gauge correctly, also the dial being marked back-to-front makes it hard to read so you need to do some mental gymnastics to interpret the reading.

Stew-Mac Nut Slotting Gauge, two thumbs up!

By
(Customer's Reviews)


The Stew-Mac nut slotting gauge is an awesome tool for dialing in the exact string height your after. I run 13-56's on all my guitars, (regardless of scale length) for all my standard E & Drop D tunings. With the gauge and a set of nut files, I can set my string height exactly where I want it (15/1,000th). The gauge couldn't be easier to use. It didn't scratch, ding or leave the slightest mark on my fretboards. I highly recommend this tool for anyone who runs heavier than 10's, and enjoys doing their own work.

Great Tool!

Worked great! Wish I would have had this long ago. No more feeler gauges. Took the time to measure all of my instruments that played great and now I can see why. I'm now in the process of adjusting the action on my other guitars. Not sure why others have had a problem with the dial reading backwards. Just count it off as you push down on the string, 10, 20, 23. Sure the dial reads 77, but who cares, just count. And yes, if you take three readings you will get a variation of .001 to .002, but then you are not building a rocket, this is close enough.

elegant , well engineered tool. No more fumbling around with feeler gauges and the fly by night, guessing game action set up. 40 years of running by "feel" is over thanks to this fine tool. I am happy!!

With this gauge I was able to set a brass nut to the correct groove depths. With the help of Dan Erlewine it was easier than I thought, and my fears went away!

Not quite what I expected.

By

The gauge works ok but there are some potential improvements that seem very obvious. 1) The gauge is marked up backwards. If the scale markings were oriented in the other direction you could simply read the dial. If you use the gauge as per instructions you have to do math in your head to arrive at the value you are measuring for. That seems silly. I have tried setting my dial to zero when the string is pressed down, which allows me to read the dial when I release the string and see the measurement value first hand. The problem with this is that it takes 3 hands to do this effectively. 2) The curvature on the bottom of the brass bass seems goofy. It makes the tool sit on most fret boards at an angle that makes it appear as if the brass block was machined incorrectly. The fact that you have to rotate the base for use on the outer or inner strings makes the angle on the foot seem like its either a bad fit or a really bad fit. A straight flat bottom seems like the best all around choice. I may machine my base to reflect this opinion. I am normally very pleased with Stew Mac tools but this particular tool seems to include unnecessary compromises that could be improved. Thanks.
