Each Masterybridge is crafted in Minneapolis using the highest quality, non-corrosive materials available. Masterybridges are designed to replace the stock bridge on these Fender® guitars: Jazzmaster, Jaguar, Mustang, Bass IV, Telecaster with Bigsby Vibrato & Jag-Stang. The Offset Mastery Bridge requires no modification to guitars originally equiped with Fender's "floating" style bridge and stock body thimbles. The bridge easily fits into vintage guitars as well as new and used American or imported guitars with these thimbles. Rickenbacker players finally have a high quality bridge replacement too!
