Re: Neck half of humbucker tilts towards pickgard
All the pics I'm seeing online show it slightly tilted to the neck, so this must be the way they designed it. I can't imagine it making that much of a difference given how slight it is, I don't see the rationale for doing this unless for aesthetics. The tilted humbucker being a feature of Van Halen's frankenstrat, which was done I believe because it was lifted out of a Gibson and the string spacing was different vs a strat with a Floyd Rose (or whatever he had before the Floyd Rose was released). As long as the strings line up with the pole pieces you're good.
Edit: Think I completely misunderstood your question, thought the pickup was angled forward. Ignore me.
