When I bought the bass in 1986 I didn't know A from C from whatever. I just knew that when I played it in the shop it felt so comfortable I had to have it. The neck isn't as shallow/thin as the '62 Jazz replacement necks I love, but it's thinner than the black/pearl block Jazz necks I've played from that era. I love the look of those, but they always felt a little weird in my hand.
