Re: Lil59 in a full size humbucker?
You don't have to take the pickup completely apart. Just unwrap the tape and loosen the bobbins just enough to be able to slide the magnet out with the assistance of a wooden match or something like that. Before you take the magnet out, check the new magnet against it to make sure you install it with the correct polarity. Also, be careful of where the pickup wires attach to the coil wires, you don't want to break them.
Then, just slide out the old magnet, slide in the new, retighten the screws, rewrap the tape and you should be good to go.
