Exploded Bridge – Baseplate, saddle, mounting post with height adjustment screw, swivel, and vented screw. Not shown: saddle height adjustment screws, rear intonation screws, and intonation screw spring.
The patented Mastery Bridge is crafted and assembled in Minneapolis, MN, using the finest materials available. Each individual bridge is inspected and tested on a guitar before being shipped to you, to ensure the best possible performance. Every part of our bridge is made of the highest quality, non-corrosive materials to protect against any rust. Because we are currently such a small shop, the Mastery Bridge is only available through this website and is not available through any other online source or retailer. Please look over the descriptions of the various parts that go into the Mastery Bridge below. Easy step-by-step installation instructions for our original offset bridge can be found here.
A close up of a completed saddle.
Plain-steel and stainless-steel saddles eventually wear grooves into the saddle with vibrato use and can cause string breakage. A steel string on a steel saddle generates heat with heavy vibrato use, and that heat will expand the metal in your string and cause it to go out of tune. We use brass for our saddles, a softer, warmer-sounding metal, but plate them with a unique hard chrome plating not found on any other guitar bridge.
Hard chrome plating is commonly used to reduce friction and increase wear resistance in parts like piston rings, hydraulic cylinders and bearing surfaces. It generates far less heat with vibrato use and your strings stay better in tune. Although much more expensive to manufacture than plain steel or “decorative chrome” found on other bridges, our saddles’ unique hard chrome-plating aids in lubricity while tuning or actuating the vibrato of an Offset or Bigsby-equipped guitar, ensuring years of consistent performance and accuracy. No other bridge manufacturer uses a plating this durable.
Saddle on the Lathe
All of the screws on our bridges are made from either 18-8 or 316 solid stainless steel. The springs are made from 302 solid stainless steel.
Absolutely no nylon plastic parts are used as components on our bridge.
Cutaway of the Mastery Bridge Mounting Post
Unlike the floating design found on all other offset-style bridges on the market, where the only metal-to-metal contact between the bridge and the body is on the bottom tip of two mounting post adjustment screws, the patented mounting post design of the Mastery Bridge fits snugly into the diameter of vintage and modern Fender-style thimbles, creating full contact between the bridge/thimble/body. This ensures your bridge will not change position during performance and remain stable during string changes without any chance of misalignment. Along with our unique saddle design, this feature also has a dramatic effect on the transfer of string-to-body energy, giving your guitar much greater resonance you’ll even hear acoustically.
Since the installation of the stock body thimbles can slightly vary from guitar-to-guitar, we’ve made our posts adjustable and removable via a vented 6-32 button head screw. The head screw contains a 1/16″ hole (the “vent”), allowing internal access to the adjustable bass/treble height screws. Like all other parts of the Mastery Bridge, the posts and screws are stainless and will not corrode.
Mounting Posts – MIJ Post for thimbles aprox .315″, and USA Post for thimbles aprox .310″
Our M1 Mastery Bridge fits all new, used and vintage American made Fender guitars. Our M2 Mastery Bridge is the same bridge as our M1, but comes with an additional set of larger mounting posts required for most Japanese made guitars.
Our uniquely designed base is CNC water-cut from a solid 304 stainless steel sheet. We then tumble them in a coarse media to de-burr and break any sharp edges. The plate edges are then buffed on a wheel and hand straight-line sanded to a satin finish. After bending them to the specified profile, our logo and batch numbers are laser printed into the metal.
Drilling the Saddles
The Original Mastery Bridge
The multi-patented Mastery Bridge features a unique 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 stainless 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 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.
The Mastery Bridge features precisely-curved adjustable saddles that allow you to effortlessly set-up to any common fingerboard radius, from 7.25" onward. Although guitar manufacturers will CNC radius fingerboards to certain specs, it’s the top of the fret that matters and should be measured, and that can change/vary overtime due to slight unevenness and eventual playing wear. Different climactic conditions can move the wood of your neck and not the frets, and depending on how malleable your fretwire is it will move or not move with it, causing slight unevenness. Varying string thickness will also affect the top of the string radius; depending on the thickness of your strings you’ll want to adjust to them accordingly. Heavy-handed players also like our adjustable saddle design because they can easily raise the bass side of the strings slightly for hard-hitting. The saddles eliminate annoying “buzzing” or rattle associated with previous single saddle bridge designs. An adjustable saddle bridge like ours is important for slight tweaking on first install and in the long run.
Our Tele baseplate is CNC water-cut from a solid 304 stainless steel sheet and stamped with our tooling to the specified profile. Our pickup cavity is undersized in tooling and then CNC’d to spec, thus eliminating any unwanted “flange” on the backside and creating a solid, flat surface. Each one is then tumbled to de-burr and break any sharp edges. Our logo is CNC engraved, followed by a series of hand straight-line sanding and bead-blasting. The area above the pickup is buffed to a mirror finish. Our baseplates blend well aesthetically on both vintage and new guitars and are intended for Telecasters with a (4) hole vintage footprint.
Please note: We currently do not offer American Standard or other style baseplates for the Tele Mastery Bridge. We do not offer the Offset Bridge with brass saddles and do not sell saddles individually. Brass saddles on any bridge will succumb to string wear over time and our brass saddle option Tele bridge (M3) is not warrantied against this sort of natural wear.
Tele Mastery Bridge
Our Tele saddles are the same as above, but with the bridge option of either electroplated brass saddles and swivels (M3 Bridge) or hard chrome-plated brass and stainless steel swivels (M4 Bridge).
Mastery Bridge for Rickenbacker®
Our M5 Mastery Bridge for Rickenbacker® mounting post screws are made of 316 solid stainless steel and mount into the body-plate via two stainless cone point screws on each end of the plate, thus securing the baseplate to the body-plate. Posts won’t loosen during performance and the bridge will stay in place during string changes. Saddles are the same solid brass material as our other bridges and feature our unique hard-chrome plating. Baseplate and body-plate are hand straight-line sanded like our original offset bridge. Optional bridge cover is hand finished like the baseplate and blends well with existing hardware.
A .050″ Allen wrench adjusts both the saddle height adjustment screws and body-plate cone point screws and the 3/32″ Allen wrench adjusts both the mounting post screws and intonation screws (included). Our body-plate has a vintage footprint and no modifications to the guitar are required.
Like our other bridges all springs and screws are solid stainless steel and will not corrode.
The Offset Mastery Bridge is easy to install. See this video for a demonstration.
