Since you just got here I guess it's understandable that you open with a question. I'm not a pickup maker. I hang out on the amplifier side of this forum. But I've been here long enough to have seen these guys on the pickup forum cover this topic over and over. You need to do a forum search. There are a lot of threads that have already covered this. Different builders have different methods and solutions so you can pick the one that works or sounds best to you.
