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.
