Do the two different types of mics that are branded ME-80s have anything in common? Looks like Senn ME-80 shotguns are used on a lot of old GD tapes. Teac ME-80s have a shotgun capsule, I'm guessing that's all they have in common. The reason I ask is I've been putting "ME-80s" in some sources and realized I might need to be more specific.
