My 68 CS Strat has AY pickups too. Is your pickup bobbin marked A.Y. or Abby? Mine are A.Y. which mean they were handwound in the CS while she was supervising. Abby means she made them herself.
Best single coils I've heard.
Actually even the A.Y. Strat sets go around $700 used now. That's how much the option actually costs on a new CS.

Nice. My situation exactly...he didn't bond with the neck cause he has small hands. I love the neck most of all, the CS relic necks are masterful. I can't even really describe the joy it gives me. The nitro lacquer is burnished to perfection like a favorite vintage guitar with 10,000 hours on it. Unreal.
I've been wanting to visit that factory. I saw a fairly long documentary on YouTube once where they explain all the custom tooling they've designed to build these things. Its a lot bigger operation than I expected. There was some really cool equipment and innovative processes being used. I was impressed.
