THanks for the advice, but the truss rod has been tightened, the truss rod honestly seems fine in terms of tweakability, its not tight but its definitely not loose either. I've tried holding the string behind the nut to see if the noise was coming from the nut. I know for a fact the truss rod isnt broken because it wouldn't be responding to tweaks, everything else has been taken apart systematically. The tuners also are nice and tight. The only things that seem loose are the springs on the bridge.
I really hope it isnt a truss rod issue, the noise isn't horrendous but I notice it.
