After doing even more research and listening to even more clips im starting to believe the pickup that Seymour wound-rewound for Edward was the Duncan JB.It was the first pickup that Seymour made in the early 70s and it was the pickup that was made for jeff beck and some of the early guitar greats at that time.The JB was a underground pickup back then(early 70s)it was also the pickup that Seymour gave those players to try,which the majority liked back then.It was also the pickup that was taken out of Edwards frankenstrat in 1989-90 when Edward went with Ernie Ball that's the pickup that Dimarzio(Steve blutcher)used to make the pickup for the Ernie Ball musicman Van halen model guitar.Im starting to really like the Duncan JB its bright(like Van halen 1)and has less bass, the mids sound very good plus it cuts very well.Its a 16k pickup-alnico V magnet, if you look at all the pickups that were made for all of the Van halen model guitars(Ernie ball-Peavey Wolfgang-EVH Wolfgang)they are all in that DC res.(16k) range.
