Neck isn't warped, nor back-bowed.....

:think: It's a 1/4sawn neck

Like I said talking out of my ass on the assumption that wood is strongest when length goes with the grain. I have no idea how to identify a 1/4 sawn or flat sawn neck. If Im wrong, Im wrong, no harm done.

quarter-sawn or flat-sawn the grain still is in the same direction as the neck, however quarter-sawn the grain is all lined up, flat-sawn you could get anything, depending on where the growth-rings of the tree were compared to the saw

Maybe that neck is flamed then and thats not the actual grain then. Kind of hard to tell since its so far away in the pic.

Ok, so two months ago I tuned it to A=440 and hung it on the wall. I have not played or moved it or anything in 2 months.

I took it off the wall just before making this post.

The neck was slightly backbowed - just a hair beyond flat.

The strings were 2.5 steps higher in pitch than normal. The low E was reading halfway between G# and A.

Normal change due to weather.

I'm no expert by any means, but if the truss rod is completely slack, then it's not doing it's job in EITHER direction. I say tighten it until it's just snug, without actually inducing any backbow.

Bingo

Actually for some reason we haven't had that drastic of a change in the weather here. It's been highs in the high-60/low-70 range, and the temp in the house has remained fairly constant.
It also did it all last winter, and the summer before, and the winter before, and the summer before, going back to when I got it in 2008.

And I did leave the rod "just snug without inducing any backbow".
