After reading some online blogs about humbuckers and the different sounds players can get from changing the magnet from, say an Alnico 5 to an Alnico 8, I became intrigued. Then I read through the actual ordered steps and after becoming familiar with the ins and outs of the process and visualizing what had to be done, I thought this might be kinda fun. But the key to really doing it was seeing how cheap these replacement magnets are - just a couple of bucks each. And there are Al Ni Co (ALuminum, NIckel, and CObalt) humbucker magnets combinations (numbers) I've never even heard of, like Alnico 6 and Alnico 9.

Swapping humbucker magnets is fairly simple as outlined by these steps:
  1. take a deep breath because you're about to take apart a perfectly good pickup and swap out the AlNiCo magnet
  2. if desired, age the humbucker now, because you won't want to mess with it too much after these steps
  3. peel away the fabric tape surrounding the coil bobbins
  4. remove the four small screws from the baseplate
  5. slowly remove the bobbins and magnet from the baseplate being careful not to damage any of the connecting wires
  6. check and align the magnetic polarity of the "as is" and "to be" magnet bars
  7. apply a light coating of wax to the new magnet and carefully replicate the placement (with correct polarity alignment) between the bobbins
  8. NOTE: if the plan is to swap baseplates, do that now by unsoldering the ground wire on the stock baseplate and re-solder the ground to the new one; then guide the conductor wires through the corner plate hole
  9. if desired, replace the plastic spacer with a real wood spacer (light coating of wax)
  10. place the bobbins and magnet back into the baseplate (six screw poles back into the baseplate holes), being careful with the wires and ensuring there's enough wax in there
  11. re-attach the bobbins to the baseplate with the four small screws
  12. make sure the bobbins are at the correct and even height with one another and at the proper angle (unscrew and adjust accordingly with spacer)
  13. use a hair dryer to carefully heat up the baseplate and top to fully melt the excess and internal wax into a proper setting (the melted wax can shift the bobbin height/angle)
  14. check the bobbins again to ensure they are at the correct and even height with one another and at the proper angle (unscrew and adjust accordingly with spacer)
  15. re-wrap the bobbins with black fabric humbucker tape
  16. replace or add any decals to the baseplate
  17. ALL DONE!
  18. check humbucker DCR with a multimeter to ensure wiring health and pickup functionality
