Neck Relief Gauge and Nut Slotting Gauge Set

About This Item

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

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!


Killer tools...!

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