Question: 90ies maple / EVH

Maybe Bigpoppa has the answer to my question. Did you change the supplier of maple in the mid nineties, I am asking because the neck my EVH from 1995 is a lot brighter than the 1995 one of my customer I have on the bench right now. It is way more like amber. It is not only the bare wood section but the headstock back as well. Just curious.
My silouette 1994 ambers more, it has about 200 gigs more on its back.
Thanks Mick
