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 towards 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 ultimate way to check nut height.” - Joe Glaser, Glaser Instruments

A simple and reliable tool.

This little device -- a rectangle of stiff plastic with precise taper on three corners-- measures the elevation of the nut slot relative to the first fret with consistent accuracy. Unlike fancier and more complicated tools, you can check ten times and get the same result every time, making the process of cutting not slots much faster and much less nerve-wracking. If you have trained your ear to judge nut height by string tapping you might still want one of these for the last thousandth of an inch. Measures differentials of 0,3,5,and 8 thousandths.
