I would think so, but then again alot of people do put them in guitars like this for this kind of tone/
It matters what kind of "metal" you're talking about. Early metal stuff IMO wold actually be more upper mids, but anything mid-80s and beyond is probably lower-mids.
Like I said, I don't have any direct experience with this, but I feel like the RY neck is just a bit raunchier than the Emerald, both in cleans and dirty tones. RY adds a bit of hair and edginess to a clean, while the Em pretty much keeps it clean, and when overdriven, it's pretty much the same deal. It just matters if you want that extra little something that the RY has or not.
