M1-KIT – MASTERY BRIDGE

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 Mastery.

M1-KIT: M1 Mastery Bridge and set of MT Mastery Thimbles
This kit for Fender Blacktop, Troy Van Leeuwen, Jazzmaster HH, Road Worn Series, ’60s Jazzmaster Lacquer and other Jazzmasters and Jaguars that are Mexican made and have a vintage style bridge and thimbles. Includes our M1 Mastery Bridge with standard US mounting posts and a set of two vintage spec 303 stainless steel MT thimbles. The inside diameter on Mexican made thimbles are slightly smaller and require our standard MT thimbles installed for our M1 bridge to work. The outside diameter of Mexican made thimbles are sometimes slightly smaller and if needed, we suggest opening the body wood holes up by drilling in REVERSE with a 3/8” bit to accommodate our USA vintage spec size thimbles.

M1-KIT: M1 Mastery Bridge and set of MT Mastery Thimbles
Guitars with an “Adjusto-matic” or “Tune-o-matic” bridge, ie: Thurston Moore Jazzmaster, J. Mascis Jazzmaster, Classic Player Jazzmaster/Jaguar, Kurt Cobain Jaguar/Mustang, etc. This kit for guitars with an “Adjusto-matic” or “Tune-o-matic” bridge includes our M1 Mastery Bridge with standard US mounting posts and a set of two vintage spec MT 303 Stainless Steel thimbles to replace your stock thimbles.

Guitars fitted with AOM/TOM bridges have threaded body thimbles that must be replaced with standard ones in order for our bridge to work. The J Mascis Jazzmaster with a TOM requires drilling holes in the pickguard to accommodate standard Jazzmaster body thimbles.

AOM/TOM style bridges were not originally designed/intended for use on Offset style guitars with vibratos. Post spacing, post size, bushing size and tolerances vary greatly on these mostly Korean made bridges and we do not make threaded style mounting posts as they do not function as well as standard USA style thimbles with our original post design. Korean specs and tolerances are constantly changing and we do not follow Korean made hardware. Our USA spec size, unplated solid stainless thimbles fit the inside diameter of our M1 bridge perfectly but are not drop in replacements for guitars previously fitted with AOM/TOM bridges as AOM/TOM bridges are a completely different design.

AOM bridges require you to dowel and drill for our standard USA thimbles.

REPEAT: We only make one vintage USA spec size thimble, if you currently have a threaded post bridge design on your guitar you will need to convert it to accept our USA spec thimbles. For more information on our thimbles visit our specs page. It is recommended a luthier replace these if you are unfamiliar with the process. It’s not very time consuming.
