I read somewhere (I think on the B side) that wix is now made in china. Napa gold too. Napa silver, unknown.
Edit: apparently Wix has manufacturing plants all over the world. Depends on the number you need if it's built in USA, Poland, Mexico, China or elsewhere.
Wix went global several years ago, which means you might get one made in USA or any number of countries where they have manufacturing plants. It was pretty disappointing. Much the same as Moog.
