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

Putting the new Nut Slotting Gauge to work on a "burn victim" guitar

Dan Erlewine shows a before and after of a 1958 Gibson that's (barely) survived a house fire. It needs a new nut, and he's using the Nut Slotting Gauge to get it right the first time.

very handy dial indicator

By
(Customer's Reviews)


This is a well designed indicator, and is a great tool for accurate setups. Someone engaged their brain wisely when they designed this one.

Brilliant, accurate tool!

By
(Customer's Reviews)


Not only did it work great for filing a new nut, but I found it works great for measuring string height at the 12th fret for action adjustment. I'm picky about getting the last few thousandths of an inch possible in lowering my action, so the gauge works great for logging slight changes to my set up.

Fast and accurate height setting

By
(Customer's Reviews)


This tool is great, it gives you ultra precise string height. If you just want to be accurate, it does that, but it also is so fast to use! If you do work at all for pay, this tool will make back it's money in no time!

Interesting tool...

By
(Customer's Reviews)


...I'm still trying to figure out how useful it actually is. Given the instructions that come with the gauge it would make more sense to have the dial calibrated counter-clockwise to give a -positive- string height reading, rather than the negative reading that's the norm. But StewMac tells me that getting such a "reverse" dial would triple the cost (really?) of the gauge, and others here have posted adequate work-arounds, so I can live with this.



A couple of other points would perhaps make this device more useful:



1) The smaller dial on the gauge is essentially useless, since it can't be zeroed by the procedure given. If it -were- possible to zero the small dial with the large one, this gauage would have a wider range, making it useful for checking action in more places on the neck than the nut, and usable with more kinds of guitar-like instruments.



2) The feet on the brass block the gauge is mounted in appear to be level in the photos, but they are not. They're cut on slant, to more easily work on radiused fingerboards, StewMac says. OK, but what about those of use who are setting up classical guitars, cuatros, bajo sextos, and other instruments with essentially -flat- fingerboards? Seems like offering an option of interchangable flat- or radiused- bases with this guage would again make it more useful.



Still, it basically does what they say it does, and it does it well, once you get used to these quirks.

Great tool...very fragile!

By
(Customer's Reviews)


This is an awesome tool and a valuable piece for anyone who regularly sets up guitars. I didn't give it five stars because of it's delicacy. I hadn't finished setting up my first guitar when I accidentally knocked it off my workbench. The dial completely locked up and no longer works. CAUTION: Be careful when using this tool and put it in a place where you can't accidentally damage it. It's too expensive to replace on a regular basis.

Fantastic device

By
(Customer's Reviews)


A fantastic and time-saving device, use it all the time. This is my second Nut Slotting Gauge, as I managed to drop my previous one on my work bench. It must have landed somehow on the top end as it became very stiff and practically useless. So take care!

Do yourself a favor!

By
(Customer's Reviews)


Make this one a priority. Okay, I must admit I had my reservations. I know you have bought at least a couple of luthier trinkets that didn't turn out to be as handy as you thought they would be. BUT THIS ISN'T GOING TO BE ONE OF THEM!!! I'd give this one 10 stars if I could. I absolutely hate messing with feeler gauges etc., not to mention my eyesight isn't what it used to be.


It's just ridiculous how easy this tool makes measuring string height and nut/saddle set-ups. I just plotted, on paper to a .000 inch, the before/after string height on an acoustic at the 1st, 6th, & 12th frets and it only took a total of less than 5 minutes for both. AND THIS WAS MY FIRST TIME USE! My customer is somewhat of a techy and his mind is going to be blown.



Also, this will make an excellent general diagnostic tool for purposes I haven't even considered yet. How about for checking a newly pressed fret for consistency with the fretboard radius for just one example. No, not all diagnostics are absolutely necessary, but it sure helps one to "know" the guitar better. That 'has' to translate into a better job in the long run.

As a guitar tech for a local music store I find the nut slot gauge to be a tool I can't live without. It makes for fast and accurate work and will always have one in my tool box.
