The Schaller GTM Bridge was the original Nashville Tune-o-matic installed on Gibson Les Paul guitars for many years, the wider body allows for more intonation adjustment in the saddles over the earlier narrow ABR-1 design, especially important for thicker strings. The bridge uses special retainer springs to prevent bridge rattle or string buzz and the saddles come without string notches to allow for custom string spacing. The Schaller GTM is supplied with 5 mm Nashville style bridge posts and body anchors/bushings.
