Let me say upfront that I know that I am going to come off sounding like an ungrateful little **** here. But here goes: Several months ago I was lucky enough to win a set of Fender Custom Shop’s new “Tomatillo” pickups in a raffle at a Custom Shop event hosted by Guitar Center Hollywood. From what I’ve read online, all of these sets have been hand-wound by FCS’s master winder Josephine Campos. And let me just say that I installed them on my Strat and I absolutely love them. Best thing that ever happened to that Strat. Here’s my question: All Josephina pickups have her signature on the back. These do not. They say “h/w bp,” which after some digging I found means hand-wound by Bricenda Pineda. Nor is there the standard certificate of authenticity that comes with FCS hand-wound pickups. This leads me to wounded whether my set are actually the Tomatillos or not. Now, I get it. I love the pickups so who cares? That’s what the GC guy who organized the FCS event basically told me. Well, I do. It’s my guitar and I like to know everything about it! So I’m wondering whether anyone on this site can help me. How can I determine which type of FCS pickups I’ve got. I know they’re supposed to be Alnico 2s. But I can’t tell an Alnico 2 from a 3 or 4 or 5. Any suggestions would be appreciated.
