Golden Age roller bridge, nickel.

This is the only roller bridge that fits the Nashville Tune-O-Matic 12" radius. It offers a low profile to keep the strings clear of the bridge body, eliminating frequent vibrato issues. Low friction brass roller saddles allow the strings to move freely and return to accurate pitch. Bridge comes with thumb wheel height adjustment studs and knurled bushings. String spread is 2-1/16", saddle radius is 12", and stud spacing is 2-29/32".
