Re: Signature
What beau said. Ant neck probably made by MJ: First, only Seymour did the Ant and CS pickups, then MJ joined the CS. My guess, its an early MJ made Ant with NJ on the label.
Now a shot in the dark: the label is not rubber stamped (pre 1997) and not label printed, but made with a type writer. My guess is mid to late 90ies made.
