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

["3 STRAIGHT EDGES IN 1: Our patent pending 3 'n 1 design sets a new higher standard for what you should expect when buying a notched straight edge. Our 2 Tri-Beam custom notched straight edges 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\" straight edge. No other product has 3 straight edges in 1 plus the breadth of guitars the notched straight edge 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\") Straight edge: Lay on top of the frets to check their flatness and assist in fretwork. All 3 straight edges 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.
