My JF 30 is my number one go-to guitar and the guitar that pushed me past the event horizon of the black hole that is my collection. I love this instrument!I pulled out my early 90’s JF-30 this weekend. It’s getting new strings and a Baggs pickup today. Still has the gigantic Guild sound.

Ah yes... that very same radiation destroyed my wallet.Maybe we could hear some of the Hawking radiation coming out of that black hole?
...Recently bought a 90’s Corona JF30. Beautiful guitar...
Please, take wyliepickett's advice here. He has a ton of knowledge with 12-ers and with BD's. Some people hate them for reasons I can't imagine and they can help level a belly and they redistribute the tension on a super high tension guitar. What he said is exactly what I first thought.... Bridge Doctors are not fixed things. They have adjustment screws and just do little adjustments at a time. And also you admit to a neck fracture which must be super stable otherwise all vibration will lose it's ooomph when transfering to the body of the guitar. So this can be fixed and that's a beautiful guitar!! Lovely.... it can get to where you want it. Glenn knows and if after many trials and tribs, if it doesn't you move on. But you can save it. You might take it to a qualified luthier and ask, but remember if the "previous owner" is giving input, then it's time to change those strings and see what you got. Check back in!!!I have Bridge Doctors in a few guitars so I'm pretty familiar with them.
Generally I see an impovement in the sound of the guitars with the BD. l don't know if it's because the BD is correcting a problem that got worse over time and the top is functioning as it was orginally intended again, or if it's due to the BD itself.
If the BD is cranked too much however it may restrict the ability of the top to vibrate.
The BD dowel tightens and loosens with a hex wrench. Try loosening it a quarter turn (counter-clockwise) and see if it makes a difference. Compare the sound with the same set of strings that are currently on the guitar. Just slack 'em enough to get your hand in the soundhole with the wrench.

There was a lot bellying below the bridge when I bought it used. My luthier reglued the bridge and added the Bridge Doctor.
The way I adjust them is to put a straight-edge behind the bridge and parallel to it, across the lower bouts, and then adjust the tautness of the rod.
Go slow. You'll see the bellying come down (less light will show under the ends of the straight-edge). The goal is to reduce the bellying. You may not be able to get a completely flat surface across the lower bouts -- depends on how the top of the guitar (especially 12-strings) has changed over time. You want to bring the bellying down enough that the saddle is at a right angle to the top and doesn't tilt forward at all.
