I have a guitar with HH configuration, I want to convert it to HS config. I want to make the three blade switch in positions, down bridge, up neck and middle humbucker and neck together. I have two singlecoil pickups came from an HSS guitar so they neck and middle pickups. the problem is I don't know which one was neck and middle pickups and also they have no magnets but I Intent to fix some neodimium magnets to the bottom of the slugs. Does the magnet polarity and winding direction matters?
