The Elmer Digital Nut Slotting Gauge allows you to take quick and easy measurements of action over the first fret with the strings in place so you can cut the nut slots to the correct depth accurately and consistently.

The brass base is specially shaped to sit over the strings and the first fret, to use, allow the plunger of the depth gauge to rest on the top of the string (tuned to pitch) and then zero out the gauge, then press the string down on each side of the fret so that it touches the first fret, the reading on the gauge will show you the amount of space that was between the fret and the string (the action). If the action is too high you can file the nut slot a little deep and retake the measurement, the accuracy and speed of taking the action measurements over the first fret will allow you to consistently cut nut slots to the perfect depth quickly and easily.

The digital readout units of measurement can be switched between metric (mm) and imperial (inch) and it comes in a protective plastic case. The battery is not included.

Game changer

I am an experienced guitar tech and at first didn’t think I would benefit from one of these. Didn’t realise how inaccurate setting gaps up with feeler gauges or just by eye could be.

Elmer Guitar Digital Nut Slotting Gauge

The Elmer Guitar Digital Nut Slotting Gauge is a great tool to speed up adjusting your nut slots to get the correct height above the first fret.
Well made and includes a nice plastic case. Unfortunately no instructions included, no info on how to fit a battery or even if one is included, no info on how to use, luckily there are plenty of videos on YouTube on the use of this tool. Definitely helps to get consistency across the Nut. Recommended.

Takes away the guesswork

I used this for accurate measurements cutting nut slots
. I checked one guitar that had been measured by feeler gauge and was surprised using this gage the results feeler gauge I thought E B G strings were .15 but using the digital gauge E was .11 B was .12 G was 16 so the gauge gives you a far more accurate measurement. The only thing I thought was a letdown was no battery supplied for the £75 you pay for it
