Neck Relief Gauge

- Accurately measures neck relief and straightness - For acoustic and electric guitar - Digital readout in metric or inches - Battery included - Gauge accurate to 0.01mm (0.001") - Easy to read - Works with new or worn frets - Made of aluminum for stability - 12" (305mm) long This gauge allows for fast and accurate measurement of the straightness and relief of a guitar neck. This allows for a better setup and more consistent playability without fret buzz along the fretboard. The relief measurement is shown on the digital readout. This can be checked as you adjust the truss rod. It accurately measures the amount of neck relief (slight dip along the length of the fingerboard) to take the guesswork out of adding or subtracting relief as you adjust the truss rod.
