Long StewMac stainless steel straightedge with bass-scale notches.
Long StewMac stainless steel straightedge with bass-scale notches.

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.
