the tone from those albums is going to be mainly from the amps and production...not from the guitar pickups...for jacksons always sound more or less the same, unless you have some really weird pickup choice. however, i dont know what kind of pickups they used back then.
From the Witchwood '96 bootleg video (both Mike and Peter playing Jacksons), they look like EMGs to me...but the quality isn't great, so I could be wrong.
