Introducing the Music City Bridge “Nut Slot Gauge.” This simple and effective tool ensures you achieve the lowest possible nut action while eliminating open-string buzz. 

With four built-in preferences of bump up above a "zero" fret - 0.000 (in thousandths of inches), 0.003, 0.005, and 0.008, the Nut Slot Gauge easily and accurately measures your nut slots' current height, with or without strings, and unaffected by action or the truss rod setting. This helps you achieve the softest feel and also the least detuning due to grip.

How to use the Nut Slot Gauge:

  1. Move the string out of the slot.
  2. Place the measuring gauge into the slot and slide the tool toward the bridge.
  3. If you hear a click, then the nut is taller than the gauge.
  4. If you don't, the nut is lower than the gauge.

"The nut slot height is one of the most critical and routinely neglected aspects of a great guitar setup. It is difficult to control the depth within the tight tolerances that are required.  You work the slot down slowly until it’s just right, but if you go too far the string buzzes and you have to start again!  The Music City Bridge “Nut Slot Gauge” provides the instant and dependable working feedback necessary to control and refine slot depth and deliver a top-notch nut setup every time."

Great tool for nut slot heights

One of my guitars wouldn't intonate quite right so I bought this tool from watching some Robert Baker videos at his favorite luthier shop. Sure enough, one of the slots was off about .003" too high. I used the Nut Slot Gauge to check the height and filed the slot a little deeper and when I got to the second lowest end, the '3' end and it didn't 'click" on it but it did on the '0' end the magic happened. Thank you for this wonderful tool.

Genius invention

Who’d have thought that such a simple little tool could make cutting nut slots so easy. Takes all the aggravation out of cutting new or saving old nuts. Yet another winner from MCB, I love it. You can’t go wrong with anything from this company. Highly recommend. Superb customer service and speedy delivery service to the UK. Thank you.

Nut Slot Gauge!

Excellent product, easy to use. First one was lost in the post but Music City Bridge replaced it record time. Well Done!

WAY better than feeler gauges!

This tool is simple, but essential. It’s much easier than trying to measure the nut slot heights with a feeler gauge set. It’s super easy to use. Just take your time when you’re filing the slots.
I can finally get great action with no intonation issues. Highly recommended!!!😎🎸👍

Nut Slot Gauge

This little tool works as advertised.. It takes the guessing out of filing the nut to the proper height. Quicker than using layers of tape or feeler gauges. Thanks to the team at Glaser Instruments for making this tool available to the public.....

Interesting tool. Maybe other folks get better results.

Tried the nut slot gauge on several guitars and experienced wildly varying results .... that surprised me. I'm not new to "nut height adjustments" and bought this tool to "improve the process". It didn't do that for me but hey, that doesn't mean it won't for you. You might have to try it first like I did. The gauge is plastic and, for some reason, really gripped my stainless frets and didn't slide smoothly. Interesting tool that may work well for others.
