I bought six of the six string PU's off flea bay, so this is a great thread for me, on a quick eyreballing it it looked like they lined up straight without angeling them. Any advantage setting them at a angle.
Do you lay the bar directly on the pickup poles or do they have to be somehow insulated (maybe electrical tape)?
Hmm... Peter, I'm curious what people will answer you with. Unfortunately, I don't have any experience with 6 string pups on 3 or 4 strings.... I have, however, lined up all 6 poles of a pickup underneath a one string diddley bow, and it worked out pretty well.
But I will add this question to the discussion in hopes of an answer: What about lipstick pickups? Do they have 6 seperate polepieces, or do they use one solid magnet inside the cover?
