RY- sure tight enough for metal, emphasized uppermids, bright topend
Holy Diver - tight enough for metal, emphasized center mids, round topend, great solotones
Nailbomb - alnico is already pretty tight, ceramic version tighter, 90's metal flavour, uppermidspike, but enough centermids (not as much as the HD), topendsizzle you like or you don't. Overall quite agressive.
