I lived in Alaska most of my life and have owned literally hundreds of guitars. Once in awhile I would get a get a guitar with a wonky neck, that would require a slight truss rod adjustment almost every time I picked it up. All were new necks with I assume green wood. If I really liked the guitar I would just wait it out. Eventually the neck wood will dry and become stable. If you don't feel like waiting you can buy another neck. But if you buy a new neck from say Warmoth or Fender you run the risk of getting another green wood neck that might be wonky too, but it's pretty unlikely. I'm a fan of roasted necks. Stable and lighter weight. I even have a roasted neck on a tele that doesn't have a truss rod. For replacements, I usually go with Warmoth or USA Custom necks and don't put Fender decals on them. I use my own. If your not a professional builder it's pretty obvious a phony decal was used. So if you need or want to have Fender on the headstock, go with Fender made.
