Those Hipshot bridges look ugly as sin (IMO 
), but i'd bet they function very well. Has anyone here used one to replace a Tilt-O-Matic? Which one would fit? If I remember correctly, the early two-point bar bridge has a slightly different stud spacing than the Tilt-O-Matic.
I like the design of the hipshots, but it is no doubt modernistic with a military-utalitarian look. But the Tilt-O-Matic is such a horrible piece of crap, I was prepared to foresake a period-apt look.
Though intended for the later sixties Evertilt with individual bridges and not the preceding bar bridge (which doesn't tilt as bad), the Hipshot Supertone fits both. I have it on my EB-3L, my EB-4 (both early seventies and with the later Tilt-O-Matic) and my Kalamazoo KB-1 (the SG, not the Bronco-like shape) which featured the original early sixties bar bridge. On that, the woodchip masonite of the body would not hold the posts/studs of the bar bridge anymore, they "ate" their way forward to a progressively greater tilt, so I tried the Supertone out of desperation. It did fit in stud spacing (Hipshot allowed for some leeway), but as the studs on the KB were not parallel but in slanted position (for better intonation with the bar bridge) the Hipshot bridge would have been slanted (it worked, but looked weird like some Dali picture) so I had my luthier drill new stud holes and voilà! But the spacing distance would have worked and the early sixties Gibsons with the bar bridge have the studs in parallel.
This is the supertone bridge that would fit, it's called "two point super tone bass bridge" by Hipshot and is not quite as big a beast as the other one:

It's an excellent piece of work and vindicates US engineers and designers from the lingering shame of the Tilt-O-Matic, albeit belatedly. Buy it and try it. Should you not like it, I'll take it off your hands, I always keep a few around and would not hesitate to use them in a project too where there is no need to match the old stud spacing. They are easy to adjust, robust as a P-40 and make comfortable handrests for pick players. And look like they came out of a Terminator picture. You will also notice an increase in sustain and tone density though lack of sustain is such a non-issue with Gibson basses that this is not really a required improvement. But you'll notice it and it feels nice.
