Wilkinson roller Tune-O-Matic bridge.
This thing is cool. Unlike most roller bridges, this actually feels nice, has some quality to it. Plus, it can work on ABR or 4mm posts (or 6mm posts if you remove the posts and install the included ones, which should screw in). Also, it's easy to radius!
Setting the radius on this is pretty easy. Get a can of V8, beer, or whatever you normally drink. I use Cherry Coke to get that nice fruity tone. Cut up the can with scissors into little pieces. Superglue a few of them together, drill a hole in it (I used 7/64" bit I think), cut to shape and you now have little aluminum saddle shims that you can fit under the saddles. You want the shims to be as large as possible, so that the saddles can clamp down on them without tilting. Should look like this:
Now you can radius the bridge exactly the way you like it. To achieve 7.25" radius on the bottoms of the strings (any set), use no shim on the E strings, 2 thickness on the A and B strings, and 3 thickness on the D and G strings.
Because this thing fits on all kinds of posts, it should be pretty easy to use this thing on a Mustang or Jaguar with no mods. Just get some M4 or 6-32 ABR posts with the thumbwheels (you might not even need one, you might just end up clamping it all the way down to the pickguard/tailpiece).
Wrap the posts with some tape so they fit snug (don't wrap the bottom, or you break string grounding), drop into the holes, drop bridge on posts. Now you have a non-moving roller bridge instead of a rocking bridge. A well set-up Mustang bridge definitely doesn't work any worse in terms of tuning stability, but the tone changes quite a bit with this bridge. The amount of energy transfer is quite astounding with this bridge, really. The third bridge stuff just comes to life, there is so much more volume. It will completely change the character of your guitar, you might even like it. I probably wouldn't do it on my only Mustang, but if I had two (and I do!)? Absolutely.
