Mastery Bridge M1 for USA Jaguar/Jazzmaster

The original, revolutionary M1 Mastery Bridge.

M1 mounting posts fit vintage and used American made Offset guitars produced from 1958-2011.

The Mastery Bridge features a unique, patent issued two saddle design not found on any previous guitar bridge. On the 52mm string spacing from E to E, four intonation-adjustment screws are used instead of six, allowing the string to freely go from the saddle to the vibrato without any chance of interference from the front of an intonation screw or back of a baseplate. Each saddle features two drop-in swivels, permitting each of the individual intonation adjustment screws to work independently for precise intonation. The deep saddle string grooves ensure that your strings will never “pop-out” during performance and are slightly fanned out on each end. Instead of around 18 lbs. of string tension bearing down on an individual saddle as found on most bridges, our bridge applies over 50 lbs. of downward string tension on each saddle. This added tension per saddle forced downward transfers more string-to-body energy, which you’ll hear in your guitar acoustically as well as amplified. The saddles accommodate the heavy-gauge strings of Bass VI model guitars and can be used on left-handed guitars as easily as right-handed.
