Okay, switched strings to DR Pure Blues (.045-.125). Was getting more rattle than I like on the B string (.125 vs .130 factory) and started drilling down into things.
Action was REALLY low, like less than 1.5 mm. Factory specs are for 2.5 mm on bass strings to 2.0 on treble. Easy fix, just remember to reset intonation after. Neck was also adjusted so there was like NEGATIVE relief...maybe because the DRs have lower string tension? Anyway, a bit over a quarter turn of the truss rod looser and all is well. I may have to tighten it back slightly after the neck finishes settling in after the adjustment, but that's easy enough.
It is definitely more bright with new uncoated strings, but the Barts are still darker than what I'm used to. I may just decide I like it that way after listening a bit.
