## 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.
- BONUS: The F-25.5 side also works on 24" scale and 22.75" scales by placing the first notch over the nut for the 24" scale and the second notch over the nut for the 22.75" scale.

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.
