Ok so i have a fender acoustic not sure which model tho i got it second hand from a friend, and it had .12 strings [no wonder i couldnt do barre chords properly]

anyway i had the action taken down and put a fresh set of .10 fender strings. Now it rattles.

So do i take the action up a bit, and which way do i screw the truss rod which is at the end of the neck [where the neck pick would be on an electric]

?
