MusicNomad Tri-Beam 3 'n 1 Dual Notched Straightedge Luthiers Tool for Guitar Necks including Fender, Gibson, PRS (MN821)

Expensive, but great quality!

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.

For working on your your guitars you need quality measuring tools. This 3 in 1 beam does the job perfectly. It's dead straight,precision ground and the it's well finished. It's aluminium so you have to be cautious with handeling the tool.

This is a precision tool no doubt. Very useful. I set up multiple guitars. I wish I had this sooner. It's made life much easier and the set ups faster.

Attrezzo perfetto, costa un po ma è ottimo, ha le due scale: Gibson e Fender, in più ha un lato diritto da usare come riga.
