Good playability is measurable. It doesn't have to be guesswork!

We designed our precision gauges so you can build, setup and repair guitars with repeatable accuracy.

Each of these gauges are available separately, or you can SAVE when you buy them as a set.

Our Nut Slotting Gauge measures the heights of the strings over the first fret, so you can cut more accurate nut slots. Also sold separately

The Neck Relief Gauge accurately measures the amount of variation from a dead flat position, to take the guesswork out of adding or subtracting neck relief as you adjust the truss rod. Also sold separately

It all depends

The Nut Slotting Gauge part of this set is wonderful. True, you must subtract the reading from 100 to get the distance and it would be more convenient if the tool generated the actual number straight out. I simply write them down as I go across the fingerboard and do the math after. In any case, this is hugely better than using feeler gauges, especially on the middle strings, if they must be snaked across radiused frets. And for 12th (or 13th) fret readings, which I consider critical to setup, there simply is no comparison between this tool and feeler gauges. It wins, hands down. Perhaps it ought to be renamed String Height Gauge. The Neck Relief Gauge is a different case, however. Those who say there are calibration issues do not ring a bell for me. I calibrated it both on a jointer bed and a straight edge, got the same result in both cases, and consider that a non issue. The instructions are clear how to do it. It takes less than a minute. The instructions are less clear, however, about how to use the tool once calibrated. It works as advertised on FLAT fingerboards. Because the feet are small, you must be careful to sense when the tool is square with the frets, but it is definitely something that I could sense easily. When the tool is square with a flat fingerboard, the readings are accurate and consistent. Flat fingerboards are found on classical guitars and most of them do not provide truss rods, so it is sort of beside the point to measure relief, unless it is so bad that you must remove the frets and plane the fingerboard. Radiused fingerboards are a different ballgame. They are found on most steel stringed instruments, which are usually equipped with adjustable truss rods, and so are the targets for the use of this tool. But the radius prevents the feet from "setting" square. Instead, you must rely upon either your intrinsic sense of what constitutes a right angle, or in my case, take multiple measurements as the tool is rocked back and forth, accepting the lowest reading as the "true" one. I proposed a solution to tech support that I thought would resolve the issue for radiused fingerboards but they say it won't work. I won't argue the point here. Instead, I plan to return this part of the set. I find it just as easy to capo the first fret, depress the strings at the 13th, and use a feeler gauge to measure relief. And ultimately more accurate because every reading is consistent. So, if you buy the set, consider yourself forewarned. There are significant limitations associated with the Neck Relief Gauge that may or may not trouble you. If I were rating the tools separately, I would give the Nut Slotting Tool a 5, and the Neck Relief Gauge a 2. In fact, I consider the Nut Slotting Tool a "must have" for anyone who is unwilling to accept eyballing to the nearest 1/64th as close enough for doing a setup. It is also great for dealing with a client who might not have as good an eyeball as yours.

Homerun! These tools make neck relief and nut depth much easier!

What's with all the drama? The underside of a quality bubble level is a planed surface. These tools ROCK!!!

Nut Slotting Gauge

Honestly! A little disappointed at first! The nut slotting gauge I received would not function when I received it! So I pulled it apart and discovered than travel stop pin had wound itself out and jammed the plunger travel. A quick tighten and away it went. Excellent! Watch out for the weight on the strings and double check with feeler gauges.

Neck Relief Gauge

The relief gauge is quick accurate and easy to use! But is limited to guitars with the right fret spacing and some Bass Guitars if the gauge can sit directly on the fretboard itself! Still an excellent tool to have in the workshop.

Double check your readings

I have used both these tools every day since receiving them but I would say to make sure you double check your readings especially with the nut gauge. Cheers for some helpful tools guys it has cut time off nut work and setups.

More accurate than my eye

I bought both of these tools in order to get my 4 guitars from different manufacturers a little more 'swap' friendly. I have achieved exactly that as I have been able to set them all up with the same relief and the same string to first fret height. I used the Nut setter a little differently to all below and my advice is as long as you are doing whatever you are 'repeatedly' then it's always the same amount either right or wrong. I first set a capo on the first fret and then measure the second fret to string height. I measure not by pushing the string down but by pushing the plunger down and releasing it. I find this way the 'down' is always the same (as long as you hold on tight to the fretboard and make sure the gauge is tight in it's base) and only the up then will be 'slightly erroneous', to which I use the strings natural resistance to push it back up by having the neck sitting horizontal on a neck rocker block. I then remove the capo and use the measured numbers + 0.001 - 0.002 from high E to Low E and have an action on every guitar now that is smooth and buzz free. Note: I play pretty light when the sound is clean and 'wring it out like a useless piece of wood' when its dirty and both ways the settings work wonderfully. Settings were used on an Ephiphone 56' Gold Top, Epiphone Black Beauty 3 pickup Custom, USA HSS Strat and 62' Telecaster. I agree that a digital readout may be better but I certainly won't be sending this unit back to soon. The Neck relief is easy to use but yes could have a larger flat (even up to 5 or 6mm as a triangular section only on the rest) to make the contact brace solid. Hey with the holes already on it and a wide flat rest you could even cable tie it to the neck for hands free adjustment

Nice, but could be improved

The neck relief gauge I found to be a little tricky. It's rather subjective as to weather you have it straight over the fret when measuring maybe a wider base would be better. Both of them I felt the gauge should go the other direction in reference to zero.the manual should include recommended settings for different instruments. I like having a number reference that I can compare. All in All these are nice tools to have, and I found them to be very helpful...

I bought one recently. It is great. It made my head spin like Linda Blair's! I can tell in a second how much relief I have, or need. I took it into a friends shop. I came back from playing some guitars and these guys had my neck relief gauge out and were using it to set up guitars. Everyone should have this tool...It will save you time and make you money. The Scientific Setup. As a scientist, I love it!

Accurate & High Quality, Nut Gauge Is All You Need

By Jon from California

I disagree with Bobby B; probably because of the approach to using a dial indicator I learned as a toolmaker. Depending on a dial indicator's ability to bottom out is an unreliable, and inaccurate approach; he witnessed why this is the case. Instead, use it up off the limit of it's range, in fact, I like to set mine in about the middle and leave it there; little chance for a mistake this way. I'm getting repeatability to 0.0005 [half a mil]. To do this, set it up so you are in the middle of the indicator range, and push down on the string over the second fret. Remember what the dial says, now lightly press on the top of the plunger, this tells you the space between the bottom of the string and the first fret very accurately. While the neck relief gauge is handy, you can use the nut gauge and a couple pieces of tape to hold the strings down. So if you want to save $$ all you need is the nut gauge. Terrific products!
