I read on another forum how some Gibson Maestros are leaving the factory with a wrong angle installed in the mechanics of it. I don't know enough about the Trems to understand how that works, but it's one more thing to urge you to take your fine guitar to a really good luthier and have it put right. >Sometimes professional help is worth its weight in groupies. (or sea Bass) That's why you see Keith Richards and Ron Wood hand their guitars to a backstage tech and receive another one, precisely tuned and set up for the next song on the set list. >All these things we're talking about are connected to each other, and it's hard for the regular player to get them all in balance. Once it's set up right, it's not so hard to keep that way, vagueries of weather and humidity can disrupt the balance, but a few tweaks can usually correct that. >Good luck, and let us know how you are getting along.
