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

Straight and flat as advertised. Beautifully made tool. Checked it on a Starrett flat stone I have access to at work and it's perfect. There is a video review of this here on Amazon that shows someone laying it on a desktop, sliding a piece of paper under it and claiming the tool is not flat..... a DESKTOP. If you lay this on a desktop to gauge the flatness of it, you are exactly the kind of person who shouldn't be using a tool like this. All you did was show that your desktopis not flat. There are probably very few desktops in the entire world that are absolutely flat. If they were, we wouldn't need to buy flat stones to gauge things. One of the more moronic things I've seen in a review here and totally worthless.In short, this works. It works well and does what it says. Not really more complicated than that.

BUY IT! I love this tri beam, It feels very comfortable and light. Well crafted from extruded and machined aluminium. It features LARGE silkscreened labels for each size neck. G-24.75 / P-25 F 25.5.I removed it from the box and fixed 2 necks within 10 mins.It is well worth the investment.

I should have bought this a long time ago! I own several guitars and basses and do my own work and set ups. This is a very well made and valuable tool. It works on many different guitar scales and has on side as a plain straight edge if needed. If you do your own set ups, get this!

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.

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.

I am very happy with this tool. I am a private music teacher who also does setup and repair work, mostly on guitars and basses. I highly recommend getting one.

Used this to start my fret leveling work.Solid piece here. Worth it.

This is a handy straight edge for guitars but the price seems to be on the high side to me. Not much material used to make it. Seems everything at Music Nomad is over priced.
