Jerry used a 25 1/2" scale guitar with a gibson bridge that had a few of the saddles slightly recut to accomodate the spacing he used. But in general it was a Gibson bridge on a 25 1/2" scale, so the Gibson spaced bridge and middle Humbuckers were used. The neck SDS1 in Tiger is only available in a strat spacing so you will notice that the pole spacing is wider. His pickup positions are also pushed more bridge side with his 24 fret neck.
Hope that helps,
p.s. something got sent your way today.http://www.gdao.org/items/show/831916
