I used to have a ME SCT with the BRW neck. That guitar vibrates and the louder you play more resonant it becomes. I can't tell what part of that came from the neck, from the finish, etc, but it was an awesome guitar. Never compared the BRW with any other kind of Rosewood nor the Pernambuco (Pau Brasil is how we call it here). But I agree with the ones who say that every little detail counts for the big picture. My question is, those woods, were very important for acoustic instruments (guitars, violins, bows, etc) and I think in that scenario, they adds more to the sound and performance to the instrument then on the electrics.
I don't think there's a Holly Grail wood for electric guitar like Pernambuco is for bows but I do think you can find a guitar with not hype woods that pleases you. Sometimes a ash body and maple neck single coil guitar is the tool you are looking for.
But yes, Aldwyn is righ, the feel of the RW neck in your hand is hand-gasm and if you add volume is the real deal.
