Precision straight edge for checking and adjusting the fingerboard Flatness (relief) on basses with many scale lengths (30/32/33/34/35/36").
Basses with baritone, short, medium, long and extra length scale can be edited with this straight edge.
The notches are placed so that the frets fit underneath and   so the precisely machined edges can reach the wood surface.
This allows the deflection of the neck to be determined exactly. Depending on the scale, it is possible to check up to 26-28 frets on the fretboard.
