MusicNomad Tri-Beam 3 'n 1 Dual Notched Straightedge & Precision Straightedge for Acoustic and Electric Guitars including Fender, Gibson, PRS (MN821)

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 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.

just what i needed

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.

Fantastic precision notched straight edge, incredible value for the money. Half the price of Stoo-Zac with more scale lengths and still high quality. The only difference I can see is aluminum vs the other brands’ steel, which is fine as long as you don’t drop it. I stumbled upon this one because I’d previously purchased an inexpensive Chinese brand (Eye-Looz or something like that) that I suspected wasn’t machined straight and I was right. Music Nomad really makes great stuff for the money. Try their nut files too! This product is absolutely worth a 5 star rating based on value for money, however I am removing one star because Amazon shipped it in a PAPER BAG. A precision tool, shipped in a flimsy brown paper bag. Yeah take your chances there. The word precision sorta goes right out the window there, doesn’t it? How many times was it dropped in transit? Buried beneath heavier packages? It’s a real “who knows” type scenario. Fret not, for there are other retailers who offer basic competence AND free shipping. Say for instance the ones that send you your product intact along with a little bag of candy? Yeah you get the picture.

So far so amazing. MusicNomad has great products. THERE IS ONE REVIEW on here, a 1-star, that shows it not being level by placing it on wooden table moving a piece of paper under it showing theirs was very curved. How flat is that regular wooden table? That's not a verified flat surface. ANY standard wooden table is going to have slight ups and downs on it. A wooden table/bench is not a know, perfect flat surface. Ignore that one. Might as well put it on your car's hood.

Very sturdy a few short edges, but nothing major. I would buy again.

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

Expensive, but great quality!

Every edge is proper straight and true. That's all that matters for this. Used on a Strat for checking neck relief and works as described.

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.
