Bridge Adjustment
The bridge on your instrument has been set to exacting factory standards for intonation and action. Rarely will your instrument need bridge adjustment unless a different gauge of strings are used or the strings are not changed often.

Banjos and mandolins have a movable bridge (banjos usually have very fine pencil markings showing the proper placement of the bridge. Most electric guitars have a permanently placed bridge with adjustable saddles.
