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."

Sometimes simple is best

I just used this today to install a Tusq nut on a Les Paul. I used it and verified it with a digital string height gauge. Using both removes all doubt of your heights.

This thing just works

Really great tool. Takes the guesswork out of cutting nut slots by allowing you to measure incrementally (and easily) as you go. If you work on a lot of nuts, this tool is invaluable.

What a fantastic tool!

Joe, I can't tell you how much I appreciate you creating this wonderful gauge. I'm just a player living in a remote area so I need to do a lot of my own set-ups and adjustments. And nut slotting it one of the hardest things I try to do. Too much nut material and the string is too high, the intonation is off at the first 3 frets. One file push too many and you're too low which puts me in Buzz City. (MCB Nut Rescue Powder will save the day!) After using your Nut Slot Gauge and my StewMac diamond slotting files ... I now have a professionally set up neck that is a dream to play. Thank you so much. I'll be going thru every guitar I own and redoing my slots. BTW, Uncle Larry sent me.

An excellent little tool

I'm an old luthier, repair dude who's cut literally thosands of nuts ...... I've tried all forms of jigs to make this job easier and time efficient but up until this point I still cut everything by eye and feel. That all changed when I started using this nut guage. A wondeful time saver! Great little tool!

Easy Peasy!

This nut slot gauge makes checking and setting nut slot height a breeze. I never thought this job could be this simple, yet still be just as effective. Thank you!

Great products my nut is cut perfect

The nut slot gauge is awesome! After watching the video i thought man that looks like would be helpful! I have been building a lot of parts casters with Warmoth or Allparts necks. Just filing the nuts till it plays well. Which worked but there was a lot of filing then putting the string on tuning it up feeling it and when it felt right inwas done. Recently I got the Slot Gauge and what a game changer no more guessing how deep to file the slots. Once I file put in pull it back and listen for the click if no click its where it needs to be. I think its neat it gives the 4 options too. If I break or lose this ill be getting another.

Game changer

I absolutely love the nut slot gauge! It is so elegant and simple and perfect for my needs. It made quick work of a couple of guitars I’ve been struggling with. Perfect results and super easy to use. What a great idea!
