The Troy Van Leeuwen Jazzmaster is a darker, more customized take on the offset, built to the Queens of the Stone Age guitarist's own spec with a striking oxblood finish and unusual dual-circuit switching. It uses a hybrid setup, a Mustang bridge with brass saddles paired with a standard Jazzmaster floating tremolo tailpiece, rather than the standard Jazzmaster bridge assembly used on other Jazzmasters in this range, so bridge parts need to specifically fit a Mustang bridge, not a Jazzmaster one. Switching is also different, a 2-way toggle for the lead and rhythm circuits rather than the usual slider switch.

Not published by Fender: bridge mounting spacing. Measure this before buying a bridge.
Matches this guitar's confirmed string spacing directly, and fits the existing bridge posts. No thimble replacement or body work needed, but Staytrem make it in two fingerboard radii, so order the one that matches your neck.
▶Why we say this
This guitar's confirmed string spacing is 52mm, matching this bridge's spec directly, and this guitar already ships with a narrower Mustang-style bridge rather than a standard Jazzmaster one.
This guitar already has a Mustang-style bridge, but a narrower one than this replacement. Fitting this could push your outer strings closer to the fretboard edge, worth checking before ordering.
▶Why we say this
This guitar already ships with a Mustang-style bridge, but at a narrower 52mm spacing rather than this bridge's standard 55.5mm. A standard-spacing Mustang bridge would likely run the outer strings closer to the fretboard edge than stock, same caution already established for the Fully-Adjustable Mustang bridge on this same guitar.
This guitar's Mustang-style bridge is narrower than the standard Mustang spacing this replacement bridge is built for. Check spacing carefully before buying, it may change your string position more than expected.
▶Why we say this
Standard Fender Mustang replacement bridges are typically sold at a wider ~55.9mm spacing, but this guitar's stock Mustang-style bridge is confirmed at a narrower 52mm. A generic standard-spacing Mustang bridge would likely run the outer strings closer to the fretboard edge than stock.
This is the standard cure for offset bridge rattle and wandering saddles, but it is not a bolt-on. The bridge sits on Mastery's own thimbles, so the ones pressed into your guitar have to come out and be replaced, and on Mexican-built offsets the holes sometimes need opening slightly before the new ones seat. Buy the version that comes with thimbles and budget for a tech to fit them.
▶Why we say this
Mastery's own fitment guide specifies the M1-KIT for this guitar, not the bare M1 bridge, because the bridge seats on Mastery's own vintage-spec MT thimbles rather than the factory ones. The bare M1 is only correct for American-made Fender offsets built before 2013. Mastery further list Mexican-built Jazzmasters and Jaguars as a case where the factory thimbles have a smaller inside diameter and sometimes a smaller outside diameter as well, in which case they advise opening the body holes with a 3/8 inch bit run in reverse before the new thimbles will seat, and recommend a luthier for the job. That makes this a body-side fitting job rather than a post-for-post swap, which is why it is not classed as a drop-in. Mounting post spacing itself is not the issue and is unaffected by any string-spacing question on this guitar. Verified against masterybridge.com, September 2026.
Matches the shape of the stock pickups, this is not the same as a Strat or Tele single-coil, so don't try to swap in one of those instead.
▶Why we say this
Jazzmaster pickups are a distinct shape and route, not interchangeable with a Strat or Tele single-coil. Fits the existing Jazzmaster route this guitar's stock pickups already sit in.
Vintage-style six-in-line tuners with press-in bushings, built for the smaller vintage tuner holes this guitar already has. Should swap straight in.
▶Why we say this
Kluson Deluxe 6-in-line tuners are made for Fender-style 6-in-line headstocks with vintage press-fit bushing holes of about 8.7mm. This guitar has a 6-in-line headstock and vintage-style tuners in vintage-size holes, so both the layout and the hole size match.
Built for this guitar's vintage-spec tuner posts, and adds string locking that this guitar's stock non-locking tuners don't have.
▶Why we say this
Manufacturer-specified for 8.5mm vintage press-in bushing holes, matching this guitar's vintage-style tuner posts, while adding a locking mechanism the stock tuners don't have.
