The RY can sure do Metal, no doubt about it. But due the brightness alot of people would prefer somthing like a NB because it has more chug, whilst the RY has more of the punch if you get what I mean. But the RY is tight enough for sure. I like to do some Trivium with mine which I have in a Ibanez S (mahagony but still small and bright).
When we say bright in a BKPs sense we mostly donīt mean piercing highs or something, but rather the a clarity and reduced bass. Not that the bass is abcent, itīs just that the most focused frequencys on the RY are the high mids, so the general characteristic can be described as bright.
These characteristics make it a great PU with a lot of cut in the mids which can be very agressive, with a nice and tight bottom which will punch but not boom, which makes it nicely fast.
I would put it in a basswood guitar (also Tim recommended it there and he knows his shitee). Also listen if your axe really is that bright, because what you can read about woods is just a good rule of thumb as far as I am concerned.
