A notched straight edge is a recent invention and a welcome one, it helps the luthier or guitar repair person to see how flat the actual fretboard is rather than just the frets and this makes for a much more precise fret job.  At Crimson Guitars we don’t just sit back and replicate what is already being made, we improve!

One side is notched to fit over long scale Fender and Martin frets and the other to fit over most Gibson and PRS scale lengths 25″, 24.75″ and 25.5″.
