Question about Silhouette bass configurations

I see it comes in both E>E and A>A. I’ve read in some places it’s the same thing just different strings. I’m guessing the nut is cut differently for each. Anyone know for sure? I’m going to send a not to CS to see what they have to say.

I have a line on a used one but I don’t know which config it is yet. Depending on which one it is I may need to swap out the nut.
