A friend of mine just picked up what is supposed to be an early 60's Fender P bass. The neck is definitely Fender, but the pickups are white/ivory with adjustable pole pieces. Anyone ever see or hear of such a thing. That is what troubles me about it. Serial number on the neck plate seems to be 60's, but the pickup looks weird to me. The neck is maple with the stripe down the back. Body is natural ash, but the bass has been refinished. You can see brush marks on the head where they have applied the clear coat. The frets are worn and the neck has definitely been played. Any ideas?
