Thanks for the response. i wasn't expecting any interest at all!!
The Book is the law. it's out of print but last time a batch was made it sold for £18 although i've seen 3 copys sold on ebay.com (u.s.a.) for between £60-£100.
I got a battered old '83 Squier JV which has got great pickups, i bought it as a wreck and got Joe White to do some repairs, it's Joe that suggested i look into making pickups.
Thanks for suggestions, there's sooo much info on the net but nearly all sites mention the Lollar book (lol).
Cheers crumb!
