StewMac 3814 Precision Notched Straightedge

When to choose it
Choose the StewMac edge when one of its documented fret scales matches the instrument you check. Confirm that the notches clear the frets before reading the board and note the side used in your setup record.
Compare the fret tops with a separate contact method. A local fret rocker can check short groups of frets, while this longer tool references the span it touches.

Questions about this product
Can I choose this edge by brand alone?
Check the actual scale length and whether the notches clear your fret layout.
What is the difference from a fret rocker?
A rocker tests a small group of frets. The straightedge checks a longer span.
Which surface matters for the reading?
Use the notched position for the board and the prescribed alternate contact for fret tops.
