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: Easier to see with old eyes - 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.

## 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.

### ⭐⭐⭐⭐⭐ Good Tool

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.
