With all respect, but in my life my wife is and will always be unique and my very only one. Calling the Alembic my other wife wouldn't do justice to either one. Especially since I feel an Alembic instrument can never be the other one, it will always be THE main one (just not the wife, that is). Funny, do female players call their instruments husbands?
In my opinion, Alembic doesn't require any tag line, just the name. Anything else would make it look like a supermarket product.
Just my opinion of course.
