Re: Prs SE trem setup
It sounds as if somebody tried to lower the action by adjusting the mounting screws, which on a PRS trem should never be moved.
The PRS trem design is great, but it's unconventional: those six screws need to be exactly the same height, otherwise the bridge plate will not be seating perfectly perpendicular to the pivot grooves. Not only might this result in anomalies with the trem action, but it also could damage the knife edge - especially on an SE bridge, which might not be hardened quite so well as core bridges or the MannMade.
The mounting screws must not be turned while there is any string tension. Probably best to have it done by somebody who has the proper spacer to reset them. But if you do it yourself, be sure to loosen the strings and pop out the trem springs first - the screws have a weak spot because of the pivot groove, and I'm told the heads have been known to snap off. Also, use something as a spacer to ensure that they're all precisely level with each other.
