Takes the guesswork out of guitar truss rod adjustment, for more consistent and accurate playability.

Adjust a truss rod without guesswork!
Our Neck Relief Gauge helps you quickly and precisely adjust guitar fretboard straightness (for comfortable playability without fret buzz). It 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.

Playability you can measure. You'll see the relief measurement on the dial as you adjust the truss rod, so it's easy to keep the neck playing its best. It's a great way to establish optimum standards for individual instruments, string gauges and playing styles.

Dependable and accurate. Designed by Don MacRostie here in our R&D shop, the Neck Relief Gauge is made of machined aluminum for stability. It has an easy to read dial indicator that's super accurate to .001". The feet of the gauge rest directly on the frets, so the measurement won't be compromised by a worn fingerboard. It's 12" (304.8mm) long, and can be positioned to take a relief measurement at either the 5th or 6th fret on a guitar fingerboard.

Instructions are included.

So easy

By \N from \N

I do set ups every day and this gauge along with the nut gauge make my job so much easier. I've heard people complain about setting the gauge to zero... if you don't have a flat surface, like a table saw, band saw, planer, or whatever, why are you even buying this? Besides, a good set up is much more than setting relief. That is just one of the factors that have to work together.

Essential Item

By Jeremy T from London
(Customer's Reviews) Thursday, March 28, 2013

I think it would help if it was shipped set up on a straight edge and marked (straight is straight) but once done if you have a bunch of guitars it is the only thing to use to set neck relief which typically has to be done at least twice a year, in the winter when the heating comes on and in the summer again. The reading is not a real number like a feeler gauge where you read 0.01" etc. but when you cross reference and get a feel or it you know what reading on the gauge relates to 0.01" or whatever you want for that guitar (keep a record). You will find that you stop bothering about the actual measurement and just work with the number on the gauge, and then checking relief is so easy it just becomes a regular thing. So takes getting used to but once mastered you will wonder what took you so long t get one.

I've been buying tools happily for many years from Stew-Mac but I got to agree with others this is one product that a short video can help clarify on how best to use. I'm sort of surprised that folks at Stew-Mac who are extremely helpful and responsive haven't done it already.

Excellent Choice

I have all my guitars with the same neck angle and action thanks to this tool. 100% Recommended

Neck Relief Gauge needs a Calibration tool

By Armando from Parrish, FL
(Customer's Reviews) Friday, February 24, 2012

Bought this a few years ago. Since you need a dead-flat surface to calibrate it, like those crazy $$ granite stones, it hasn't aided me much at all. Stew-Mac need to repackage this with something to calibrate it against(what ever that may be) to make it worthwhile. Until then, it sits in my tool drawer.

better instructions?

This gauge works great...The problem with others users reviews is ,they needed better instructions....You have to rock the gauge back an forth to get the correct reading on a rounded fret..The correct reading is the largest number {change} from your zero point..Which is usually a minus with some relief..Finding a flat surface for calibrating can be a problem..if you have a good straight edge, that will work..Better instructions are needed..

Faulty instructions

By RalphWB from New York
(Customer's Reviews) Friday, December 02, 2011

I had the same difficulty in getting an accurate reading as the two other negative reviewers. Also, I don't have a truly flat surface to calibrate it. And the instructions don't mention that the lowest reading is when it's flat. Maybe it should be obvious but it wasn't to me. I wonder why it wasn't mentioned to me when I called about returning it. I got a straight edge from StewMac and that works fine.

You need opposable thumbs to use this tool

By Steve West from Colwich, Kansas
(Customer's Reviews) Wednesday, October 05, 2011

This tool works great. I am shocked at the reviews of JukinJimmy and SteveC, saying they can use it. You have to learn to coexist with any tool. Sure, it must be held steady by one hand to obtain a good reading. If you are not certain if it is flat across the frets, rock it back and forth. During this rocking, the lowest reading is when it is flat. A wider base would present a new problem by rocking fore and aft across the curvature of the fret.
