About bridge & tailpiece measurements

Bridge and Tailpiece Measurements Snippet

String spread is the distance between the centers of the outer strings on a bridge or tailpiece.

Saddle radius determines the arc formed by all the individual saddle heights, and is similar to the measurement of a fretboard.

Stud/post spacing is the distance between the centers of the mounting posts of a bridge or ‘stop’ tailpiece.

Tip: Slotting Tune-o-matic style saddles
Nut slotting files work great for metal saddles. Choose your file size as you would when slotting a nut: use the same gauge as the string, or a few thousandths larger. After filing to the desired depth, we suggest polishing the slot with Mitchell’s Abrasive Cord to remove file marks and burrs.
