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

Happy Camper

A bit pricey but way functional. I hooked an ohm meter to it so I get an indication of initial string contact. This really helps on any string ht. measurement up the neck where the indicator movement's weight effects the string bend. Next an LED.

A must have for nut making!

Kinda pricey but worth every penny! If you want to be consistent and accurate on your first fret string clearance you must have this. Takes the guess work out of the nut slot depth, and blowing a nut!

Why did I wait so long?

I bought this a couple years ago and promptly put it away and forgot about it. In a busy commercial shop it's easy to do that. Just recently the question came to our shop about standards of string height at the nut, i.e. when making a new bone nut for example what do we tell our customers our standard height is? I've just eye-balled it all these years and done just fine but telling a customer you're doing that just doesn't fly. So I got the gauge out, dusted it off and quickly oriented myself to its usage. I now literally use it everyday. When a guitar comes in for a setup for example we make pre and post set up measurements of action so customer has Thee facts (the StewMac neck relief gauge is also essential for having true numbers). All this is so much easier and more accurate than a feeler gauge.

For those having purported inaccuracy issues you must set the device in place and make sure you don't bump the gauge when lowering the string to check - the tiniest bump will give you an apparent discrepancy. After this user acclimation the device is perfect - the needle does not deviate.

My take on operation is I never bother to zero the gauge - there's just no need. Since I'm reading backwards from zero anyway I just make note of the needle position, push down the string and it's easy to see how far it traveled via the markings. Honestly I would do better without any numbers and just the markings with the larger hash marks for the 5's but no biggie. So pleased I've discovered this after two years - Must have for me.

Ok, a little melodramatic on my part. Honestly though, this gauge easily paid for itself the first week I had it. It saves not only time, but stress as well. I feel much more confident in my depth filing with this tool in the shop.

A great tool idea, but falls short on quality.

I bought the bass model, with the expectation that this tool would make it easier for me to set up accurate, low action at the first fret, as well as keep tabs on action at the 12th fret.

The first problem I've encountered isn't StewMac's fault: the slots in the brass bass don't work well with my P-Bass's vintage-spec 1-3/4" nut width. I suspect the tool base was dimensioned and slotted to work with the more common 1-1/2" and 1-5/8" nut widths.

The main problem I have with this product is the quality of the supplied dial indicator. In short, it appears to be a very cheap off-shore, no-name unit, and it offers no accurate repeatability. Meaning, when I zero the dial, then run the gauge through it's travel, then back to it's original resting point, the needle consistently registers a good .002"—.004" off from zero. A better quality gauge wouldn't do this. I attribute this to the gauge's inexpensive construction, as well as the lack of any return spring. If this gauge utilized a light return spring, I think it'd work better, and the spring wouldn't create enough downward "push" to move an average bass string. Still, construction quality of this gauge's internals would be a problem.

I think if the overall gauge quality were more on-par with other StewMac tools, this would be a very useful tool, and I really like the idea of employing a standard "thou" dial indicator for precisely measuring string action. However, for me to make this tool work, I'd need to mod the brass bass to accommodate my basses nut width and string spacing, and I'd have to purchase a good quality indicator — which will run $80-$90.

This Nut Slotting Gauge takes all the "guess work" out of a very important part of the "set-up."

No more am I putzing around trying to figure out if the nut depth is 1/2 mm. This nut gauge measures in 1/100th's of an inch. Accurate every time, just don't cut too deep!! :)

I’m amazed how much better my guitars play with the nut slot heights dialled in to the thou of an inch. I’ll never slot a nut again without it!
Thank you again Stewmac!!

Precise and that's all.

We've try it at the shop a few weeks ago. We don't use it the way stewMac explain, we prefer to check with the dial the exact height of the 1st fret. Then, we install the gauges that determine the height of the bottom of the nut, and when shaped, the gauge that determine the proof of the slots. Big time and quality saver! The process is written and used even by our new apprentices with no failure.

I've been using this for years, but always thought the base curve for the fretboard should be in the other direction. Instead of the gauge on the shorter side of the base, I felt it should be on the taller side. IMHO
