### ⭐⭐⭐⭐⭐ Well made, accurate, useful and a very good value!
*by F***. on May 24, 2023*

I bought this after reviewing many others in part because I'm familiar with the MusicNomad brand. I was not disappointed in what I received. This is a quality instrument that anyone who works on guitars needs. It serves two purposes. The 1st is in checking the fretboard (wood) for level before you then (2nd) check the frets for uneven wear. It's important to first adjust your truss rod so the fretboard wood is in a fairly straight plane before you consider taking any material off of your frets. This tool lets you do that. Its well made and the surfaces you are checking with are precision machined. I checked mine against a L.S. Starrett 24 inch straight edge and it looks excellent which is expected. One note worth mentioning is this is crafted from an Aluminum extrusion. It is a quality material and most likely 6061 aircraft Aluminum that is heat treated for strength and hardness. However, this material is malleable and will dent or ding if it receives sufficient impact with a like hardness or harder metal (your frets are harder). It's important to treat this gauge as you would any other precision measuring instrument. That said, every other one of these I've seen that is affordable, is also made from Aluminum. Yes I would buy this again and recommend to my home Luthier friends.
