Another set of Fender Noisless just arrived. One thing I noticed immediately was they had ceramic mags. The other set I've got doesn't. I had noticed a rough texture to the bottom of the first set of pups but I assumed it was associated with padding and the thought someone may have removed ceramic mags never crossed my mind - but now I'm assuming that's the case. I can't find a single pic of the bottom of a Noiseless pup or mention of the ceramic mag in descriptions on the net. Does anybody by chance KNOW for a fact whether ceramic mags are standard on Fender Noiseless J pups (gold script bi-poles) or if possibly that was done for the VB signature bass?
