To set the string length or intonation, loosen the screw
that clamps the bridge saddle in place with the supplied T-handled 3/32
Allen wrench. If the string plays sharp, slide the saddle back to make the string
longer. If it plays flat, slide it forward. Re-tighten the saddle screw. The
Piezoelectric elements in the bridge are delicate, so be careful. The eraser end
of a pencil is a safe tool for sliding the saddles.
