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

easy to use

Nice tool, easy to be precise and consistent in your setup. I just would like StewMac to offer METRIC version of the gauge, or a swappable gauges face, as it would be a way cheaper option.
that's why I gonna give 4 stars.

Spendy but worth it

I hesitated a while before dropping the chase for this, but I wish I had jumped sooner. No more feeler guages or intuitive guesses. Accurate and easy. Worth the cash. If you’re on the fence go ahead with it. I don’t think you’ll regret it.

Handy tool to have

You're dealing with thousandths of an inch so a lot of things can affect your accuracy but It was easy to be sure each guitar is closer to correct than just "in the ballpark"..
I have a lot of guitars to maintain so I'm glad to have gotten this.

So nice

Extremely precise.

No more fumbling with feeler gauges, check.

No more squinty faces trying to read, check.

Once you get used to the delicate handling, i.e. not touching the string, trying to turn the dial (it's new and stiff) to zero (without tipping or touching strings) it works wonders....

But guess what else it does well?

It measures fret crown over the fretboard.

1) start by zeroing it over the fret, not the string.

2) turn it 90° as seen from a top view and let the plunger touch the board.

3) be aware that your board may not be level and the measurement will be off.

Great tool very accurate.

I am an amateur luthier that works on my own guitars. I wear glasses and have a hard time reading measurements. The Nut Slotting Gauge has helped me immensely. The readings of the string height at the first fret in relation to the nut are very accurate, and leave no guesswork. My setups are very accurate and the guitar sounds awesome. I would recommend the Nut Slotting Gauge for any shop. You will not be sorry you purchased it. This tool saves a lot of time. Great tool guys, you've helped me out a lot with this tool. As always Stewart MC Donald is always my first choice when I have a problem with a guitar, either in advice on the phone or when purchasing an item. Thanks Guys. Very satisfied customer. Sincerely Yours, Roy Sorenson

Elegant tool

This is a Beautiful, Beautiful, Beautiful device. Seemed pricey until I tried to imitate it's function by fashioning a block of wood and using a caliper, then is seemed like a deal. After checking the price of dial indicators on the Internet, it seemed like the deal of the century.

To a newb, such as myself, I can measure how much material those wonderful nut files take off with one or two strokes. I've ruined a few nuts underestimating their efficiency.

I'm discovering other uses for it as well.

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.
