Setting Intonation - Parker Fly Handbook

Setting Intonation

To set the string length or intonation, loosen the screw that clamps the bridge
saddle in place with the supplied T-handles 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 piezo-electric elements in
the bridge are delicate, so be careful. The eraser end of a pencil is a safe tool
for sliding the saddles.
Intonation is affected by changing string gauge, truss rod adjustment, action
height, or how hard you press the strings.
