StewMac 3813 Notched Straightedge for 34 and 35-inch Bass

When to choose it
Choose the 3813 if your bass matches one of the two stated scale lengths. Make sure the notches clear the fret wires so the tool uses the intended board surface as its reference.
The 22⅝-inch tool covers a longer span than a guitar straightedge. Compare the contact surfaces independently if you also need to check the fret tops.
