Lots of hearsay going around that the magnets in the Fidelitron pickups Fender puts in the MIM Cabs are ceramic. I always thought they sounded too sweet for this to be the case. So I called up Fender consumer relations today and asked them myself. The gentleman told me that he couldn't reveal much in the way of specs, and that they are a Korean made pickup, but that they do indeed use alnico magnets. For those interested!
