    Hello Craig,
    you're right: the rear part of bridge it's in contact with the guitar body, and that's wrong. This can happen for many reasons: too low tension of strings, or too much tension of springs under the bridge, etc.; in my opinion, if you are not expert about settings, is better remember PRS indication: "If you are unfamiliar with making these adjustments, we recommend that the guitar be taken to a qualified repair center."
    Nice guitar! Ciao :beer:

    Yes, the bridge will raise up by reducing the tension (loose screws) of the springs.
    But so many factors are involved about the correct bridge position, so this could be not enough... it's the raison why i've only stoptail bridges!
    Sorry for my english, i hope you understand me...
    The screws are NOT the little screws on the backplate, but the big screws in the tremolo cavity, which fix the springs on the wood.

    A quick and easy way to do it is to find a few pieces of card that come to about 1/16" thick. Use the tremolo arm to raise the rear of your bridge and put the card underneath. Check that your bridge is level or as level as you want it to be. Tune your guitar. Now, with the guitar vertical - sitting on the strap button - gradually back out the screws in the claw. Do it evenly, one screw after the other, a half-turn at a time. When the card falls out, the tension between the strings and the springs in the back will be even. You should only have to make small adjustments to the tuning to get it perfect.

    This works with all kinds of tremolos including Floyds. If your bridge were sitting too high at the rear, you'd have to screw the claw in tight first and then do this, but the process is the same.

    Visually check that trem is resting in thegroove of the six fulcrum screws. All 6 should be the ssame height just dont adjust them until you loosen all the strings or you will ruin them. Loosen each claw screw 1/2 turn at a time until the trem starts to lift off of body. Tune to pitch. If trem isn't level adjust screws then retune.

    I have a prs that came to me with claw screwed tight to body. I think my springs are shot because of that. I tune to Eb and the spring claw is only 1/8 away from cavity wall with 4 springs and 10s. I think if I tuned to standard pitch or went to heavy 10s I would run out of adjustment.

    Trem isn't as stable on this guitar either.

    It sounds like you just need new springs.

    Yes I think you're correct. I replaced the fulcrum screws because they were slightly worn so I will order some new springs see if that helps tuning stability.

    That is the link John is referring to: http://prsguitars.com/forum/showthread.php?11317-How-to-install-a-Vibrato-Bridge

    The way I understand it is you either changed to a lighter gauge strings, or downtuned the guitar. In both cases I would loosen the two screws in the spring cavity just a little.
    If you changed your strings to a lighter gauge, intonation might need a setup as well...
