That makes sense, but I'd still call and ask. Best to get the info straight from the horse's mouth.
I have an all Rosewood neck here where the fretboard wood is dramatically different than the neck meat. The people who've seen it think the fretboard is Brazilian, but I'm not knowledgeable enough to say. I can't imagine Warmoth shipping something like Brazilian in place of Indian, but who knows? Maybe they screwed up.
In any event, Rosewood is sort of a generic term, and its presentation/quality varies widely. Even WalMart guitars will have Rosewood fretboards, but they're nothing like what you'd get from a premium supplier like Warmoth/PRS/etc.
