Hey all, I just ordered an A8 magnet for my JB, I also switched out the screw polepices with the hex heads from my Humbucker From Hell, I basically put the screw type in the coil closest to the neck in my HFH and put the hex heads in the JB. I know that the new magnet will alter the pup a bit, but what should I expect from the polepieces being traded? Will this have an affect on the tone as well? Or was it just a cosmetic change.
