I have heard different stories on how and why this pickup was made. Obviously the Pearly Gates is modeled after the pickup that Billy Gibbons has in his 59 Les Paul. But whenever I see a quote from Billy Gibbons, regarding Seymour Duncan, it is about how he loves the Antiquities. I have heard that Seymour Duncan actually used Billy Gibbons pickup and reverse engineered it, or analyzed it somehow, but that seems a little far fetched to me. Why would Gibbons allow anyone to take anything from his prized once in a lifetime guitar? I have also heard that Duncan wanted to make a 59 replica that had a few extra turns on it, making it have a little more sizzle. I was wondering if Mr. Duncan intended to duplicate the pickup with Gibbons permission, or just make a pickup that sounded like it, or even develop this pickup with the intentions of Billy Gibbons using it some of his other guitars.
