MusicNomad Tri-Beam 3 'n 1 Guitar Notched & Precision Straightedge (MN821)

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.

Straight as an arrow. Notches fit over frets as they should. The notches were all even when held against a straight edge and on a flat machine table. Perfect for adjusting guitar necks.

This thing is AWESOME. I tried it on a couple of my guitars and got em dialed in fast \m/ Highly recommended. It's a tool that you don't know you need, until you get one.

I was having trouble seeing if the frets were level with my $15 level. It's straight and notched for frets but the issue was that it's shiny gray! The light glare off the frets made it hard to see the gray on gray. This one solves the issue and it's a quality product. Nice and straight and a bit easier to hold than the flat straight edge.

I have always performed truss rod adjustments by using the low E string as a straight edge, but I have never had confidence that this was as accurate as I would like. The MusicNomad tool has helped a lot, and allowed me to dial in to the exact relief that I want out of each of my guitars. I have used it for Gibson, Fender, PRS, Ibanez, and Epiphone successfully to validate some of my prior adjustments, and make tweaks as necessary. This is a much better value for a casual guitarist compared to the StewMac versions.

Not perfectly straight but damn close. It's good enough for what it's designed to do.

With both a Gibson and Fender fret clearance scale as well as full straight edge, a very useful item at significantly less than comparable options. Not inexpensive, but good value if guitar setup is going to be a common activity.

Excellent luthier’s tool

Well-engineered straight edge, does the required job perfectly.

Expensive, but great quality!

L'outil est de qualité et repondra à votre besoin mais vendu à un prix vraiment trop élevé.

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.

Tomé un curo para poder darle mantenimiento a mis guitarras eléctricas, esta herramienta es básica, es la base de hecho de una buena calibración. Me encanta que se adapta a diferentes tamaños de mástiles (o brazos), en mi caso solo tengo Fender, tanto strat como un par de teles, y jaló al 100.
