Nut Slotting Gauge

Regular price $62.99

The Digital Nut Slotting Gauge quickly and precisely measures the heights of the strings over the first fret, so you can file nut slot depths more accurately than ever before. That means easier, more consistent playability, that you can custom-tailor to individual instruments and playing styles. No more guesswork or ""eyeballing"" the string heights, and no more searching for elusive combinations of feeler gauge.

It features an easy to read digital indicator with a ZERO button and a INCH/MM switchable button, accurate to .0005""(0.01mm), it features high accuracy, direct and reliable reading. The machined brass base fits flat over the fret and strings for a more accurate reading. And rests securely on the fingerboard.


Digital Nut Slotting Gauge Instructions

The Digital Nut Slotting Gauge precisely measures the heights of the strings over the first fret, so you can cut accurate string slots in the nut.

How to use the Digital Nut Slotting Gauge:

Your most accurate measurement is at the first fret. Although this tool can be placed at other points along the neck, we recommend using it at the first fret for maximum accuracy. The proximity to the nut keeps the string rigid at the first fret and gives the most accurate reading. As you move up the neck (the 12th fret, for example), the string is much less rigid. Even the weight of the digital indicator's plunger is enough to push the string down, giving a false reading. For taking measurements higher up the neck, we recommend the String Action Gauge.

Step 1:Turn on the digital indicator. Set the Digital Nut Slotting Gauge over the first fret, with the indicator tip resting on the middle of a string. Press the Zero button to zero out the readout.

Press the string down to the first fret. Press on both sides of the fret, to be sure you get an accurate reading. The digital indicator now indicates the height of the string over the first fret.

Step 2: Pull the string out of the nut slot. File the slot deeper, replace the string and take another reading. Repeat until you reach the height you need. Note: If the strings are too high at the first fret, they can be difficult to play, and if they're too low they can buzz. The strings on electric guitars can generally be closer to the first fret than on acoustics. This is also true for players with a lighter touch vs. players with an aggressive style. The bass strings should gradually sit higher in the nut than the treble strings.
