Anyone ever tried this? I mean putting a skinny bar magnet on the bottom of the lower bobbin. MIM Strat pickups use non-magnet polepieces with bar magnets on the bottom, but what about the bar magnet plus pole magnets?
If not a magnet, how about just a piece of metal bridging the polepieces?
My idea is to boost output and midrange, peel a bit of the top-end clatteriness off of the pickups, but without losing the tight bottom end characteristics of the A5 magnets.
