Gibson Accessories ABR-1 Tune-o-matic Bridge

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.

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.
