Yes Joe you are right, the SDS-1 is taller and that can cause prob's with some bodies with shallow routing. With my Fender Std. Strat bodies it just barely fits (with original swimming route)--it touches the bottom but the strings still clear, albeit with less room for adjustment than I would like. I think it is too tall for vintage (3 x SC) Fender bodies, though I stopped when the pg didn't sit flush for mounting w/o adjusting the pups higher in pg. If routing is done, only a little needs to come out--there is plenty of wood so routing the body too thin isn't an issue.
