SLAT90 and SLATQM: Difference in construction?

[stefan5]

Hi guys,
first of all, I´m quite new here, Stefan from Munich, great forum!
Maybe someone can help me: Is there any constructional difference between a slat90 and a slatqm (apart from pick ups)?
Í´m asking that because I own a slat90, and some mini-humbucker and so I think about changing the p90 someday with mini-hums to see how it sounds. (Guitar is great with p90 also.)
Thanks a lot!
Stefan

I believe they are 'structurally' built the same way. Only difference might be the kind of tops on them and the obvious pickups.
