Various pickup makers make pickups with neodymium magnets, which are heavy duty magnets designed to drive preamp tubes (note, tubes, you can blow the preamp of solid state amps using these, or according to CorduroyEW. Same for the SD, there's a version of the Blackouts that are really heavy duty, they suggest pairing it with a different pickup as it can't get a true clean sound.
