I plan on building pickups soon, but I have a few gaps in my knowledge that need filled beforehand.


A few I can think of at the moment:

After assembling the bobbin, do I need to put a spacer in between the pole pieces and the windings or can I wind directly around the pole pieces?

What type of metal should the pole pieces be made from?

Does it matter what material the bobbins are made of?
