The original Gibson bridge, right from the source!
The ABR-1 Tune-o-matic bridge was the brainchild of legendary Gibson president Ted McCarty in 1954, setting a standard for simplicity and functionality that has never been bettered.
The ABR-1 is installs directly into the body of the guitar using a separate stud and thumbwheel, providing a firm seating for the strings and allowing players the ability to adjust and fine tune intonation and string height in a matter of minutes. It also yields a great union between the strings and body, which results in excellent vintage tone and sustain.

About bridge & tailpiece measurements
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.
