Agree with much of the above. A possible clue is the time between the OP's ownerships.
When I've changed strings, bridge, sound post et al on my DB, it always takes some time before it settles down again.
I think this also happens to a lesser degree with solid body BGs. After playing a freshly assembled parts bass for a few weeks I would retighten the neck bolts, and bridge & tuner screws. It also seems to me that the entire physical continuity between tuners and bridge improves with playing.
I am a little dismayed when I see an old collectable bass, dismantled by it's seller to clean or reveal some artifact.
