If you are having trouble determining what block or bridge you need, the following compatibility chart and information may help. Our parts are made specifically for Fender guitars, but because they are modular many models end up being 'parts guitars', that are no longer unaltered factory instruments. It is vitally important to measure your bridge, as 'looks like' is not a reliable way to purchase a product.
When looking for compatible parts, Fender sometimes adds to the confusion by using the same words in a different order for different model guitars. Please research your guitar model independently as well as referencing the chart and measurements below.
If you are building your own guitar from an aftermarket body supplier, the two primary body routes to consider are Vintage or American Standard.
If you are working on a Squire model, excluding the Classic Vibe series, you must measure your bridge and body.

NOTE:
If you're building or retrofitting a guitar with vintage mounting and want to use standard humbuckers, the V/N bridge provides the correct string spacing to use with those pickups, and no alteration to the body needs to be made.

Important Strat Dimensions

For you to choose the correct Callaham bridge for your instrument, you must determine your body thickness, string spacing, and mounting spacing.

For any of our strat bridges to fit your guitar you first must have an 1 3/4 inch thick body (44.5mm). If your body is under 1 3/4', you will need a cut down block. Now nearly all Fender strats are 1 3/4 thick. Only certain Squire models are not. So if you have a Squire, be sure to check.

Above: A Callaham Stratocaster with a 1 3/4 inch (44.5mm) thick body. All our bridges are designed for use in 1 3/4 inch thick bodies, the industry standard.

Above: A Squire model with a 1 1/2 inch (38.1mm) thick body. A bridge for anything under 1 3/4 will require a custom cut down block.

String spacing is the distance from E string to E string, measured at the saddles.

String spacing can be checked at a number of places. It is the bridge plate that determines string spacing, not the saddles. An easy place to take the measurement is at the intonation screws. The photos show a vintage '54 Strat and a newer Squire model. Measure center to center between the two E string screw heads. The vintage '54 is at 2 7/32' (56mm) and the Squire is at 2 1/16' (52mm).

Mounting spacing is the center to center distance between the two outside pivot mounting screws.

Again, mounting spacing is done center to center between the two outside pivot mounting screws. Vintage is at 2 7/32' (56mm), and the Squire 2 1/16' (52mm).

Knowing these measurements will get you the correct replacement bridge. Please note however, we only make six pivot bridges. For American Standard and American Deluxe Models we make upgrade kits. The American Deluxe models have a pop-in arm and always (at least until now) have offset saddles. The American Standard model has a thread in arm and depending on the year offset saddles or center intonation saddles.
