I am very keen on getting a set of these. I am sure every one of the 800 sets is awesome, but is there any known differences in earlier vs later, ect that would point someone towards looking for a set number in a certain range? Stuff like different wire supplier, magnet vendor, etc that gives one set a slightly different sound to another. I had the great pleasure and honor to have Seymour wind me a set of strat pickups in person at a guitar show where he had a booth back in the day and although I know he isn't winding these, I know anything special edition from his shop is top of the line. Thanks.
