If your talking those series of pickups they were the same pickups made in house at jackson there was no difference between the import and USA made ones
The Japanese Jackson pups will go peepee in your Coke.....
Welcome (to your death)! :beerchug:
I can't answer your question, I had a J90C once, never had "Made in USA" or anything on it, and I've never heard of any having that either. It sounded okay.
Our man! :beerchug:
From what guitar was your J90C? Had it any inscriptions/stickers?
