The original, revolutionary M1 Mastery Bridge. M1 mounting posts fit American made Offset guitars, including new, used and vintage.

Problems with your current bridge? You’re not alone. Since its conception in 2008, the multi-patented Offset Mastery Bridge remains the industry leader and most trusted Offset bridge in the hands of touring musicians around the globe. Luthier designed, our original Offset bridge eliminates the buzzing associated with previous saddle designs. Your strings won’t fall out of their grooves — no matter how hard you play.

All of our Offset bridge saddles are made of solid brass and we plate them with a unique, self-lubricating hard chrome plating not found on any other guitar bridge. Hard chrome plating demonstrates excellent hardness and lubricity, and is the premier engineering choice to reduce friction, minimize wear and eliminate the heat/tuning issues caused by vibrato use string/saddle friction. Our hard chrome plating also protects the saddle from wear, preventing grooves formed in the saddle over time, versus stainless steel and plain brass.

The patented non-rocking post design along with Mastery’s patented two brass saddle design has a dramatic effect on the transfer of string-to-body energy, giving your guitar much greater resonance that you’ll even hear acoustically. AND THAT’S JUST THE START. Check out our specs page to learn more, and see why veteran guitarists such as Nels Cline & Jeff Tweedy of Wilco, Elvis Costello, Troy Van Leeuwen, Bill Frisell, Thurston Moore, as well as thousands of others use the Mastery Bridge.
