Review: Invaluable! - 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!
Review: Well made, accurate, useful and a very good value! - 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.

## Features

- 3 STRAIGHTEDGES IN 1: Our patent pending 3 'n 1 design sets a new higher standard for what you should expect when buying a notched straightedge. Our 2 Tri-Beam custom notched straightedges cover most all electric and acoustic guitars such as Gibson, Fender and PRS. Plus, on the 3rd Tri-Beam, you get a 17.6" (44.7cm) "notch-free" straightedge. No other product has 3 straightedges in 1 plus the breadth of guitars the notched straightedge works on.
- PERFECTION BUILT INTO THE DESIGN WITH LONGER LENGTH AND NOTCHES THAT COVER MORE GUITARS: Check the flatness of your fretboard to assist in fretwork with our notches that cover 17.6" of the fretboard and touch the fretboard between 22 fret slots which is more than most other products on the market. You can also use it to measure neck relief to see if you need to adjust the truss rod.
- Custom notch design is like no other specification and works for most electric and acoustic guitars. F-25.5 fits all 25.34" to 25.625" fret scale lengths. G-24.75/P-25 fits all guitars with fret scale lengths ranging from 24.625" to 25".
- 17.6" Precision Flat ("notch-free") Straightedge: Lay on top of the frets to check their flatness and assist in fretwork. All 3 straightedges are precision ground to ensure smooth flat edges within an accuracy tolerance of +/-.00125"/ft.
- Designed by our Sonoma, CA (USA) team, the premium quality 6063-T5 Aluminum has a blue anodized finish that is extremely durable, abrasion resistant and does not peel or chip. Imprecision is eliminated through single setup, continuous 5-axis CNC producing flawless features on all surfaces of our innovative triangle 3 wall design that is easy to hold and flex-free. Convenient hang hole included.

### ⭐⭐⭐⭐⭐ Flat. Don't believe video review.
*by T***J on March 18, 2025*

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 desktop is 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.
