Goto 510 bridge problem

[Sixstring]

Sense I sold my Ultra I have been playing unplugged and have noticed a buzz or rattle with certain chords mostly when played in the middle of the neck and goes away when I place my palm on the string saddles and add some downward pressure. I have eliminated the springs and Tremol-no which only leaves the saddles, top plate and block. Has anyone else come across this issue with this particular bridge? It's driving me nuts and would like to fix it.

Found the fix for this over at TGP... The Locking set screws in the posts were lose.

EDIT: Found another issue with the Tremol-no... the clamping rod that attaches to the claw was vibrating also. The quick fix for that was to move the stop all the way to the claw and tighten the set screw.
