Precision steel square for instrument work

Square up parts, lay out string spreads, and accurately set up tools. 1/32"-increments on one side, millimeters on the other.

Lies flush on guitar tops

Unlike squares with a thin blade and thick handle, our Luthier's Square works flat against a guitar's surface.

Set up tools, true up parts

The small size is handy for tight spots. The notched inside corner fits against corners snugly, with no wobble.

Measure nuts, saddles and pickups

Small vertical rulers are useful for measuring height on saddles, nuts, and pickups.

Easy to read

Satin chrome steel with sharp black etchings reads well even in poor light. Accepts pencil marks nicely, too.
