I'm considering the exact same thing- putting an Alnico 2 in my JB. I know that www.ampge.com has the magnets, but does anyone have any instructions for how to go about switching the magnets? Someone once said it's "not hard", but the one site I found that gave instructions were for Les Paul pickups and while it looked somewhat involved they had steps for rewaxing and that sort of thing that I imagine I wouldn't have to go through. Are there any instructions specific to SD pickups?
Thanks!
