Wow, I'm not even sure. I got my Mezzo in April and it's bottom isn't one piece of vachetta like the 1st one. It must have been REAL recent.
yes it did. Used to be 3 pieces and now its one. Not sure of the date that it changed. Mine piano was from 01 and had 3 pieces.
I got my Mezzo early this year and it is also 3 pieces like the 2nd picture...
It changed about 3 years ago, the same time they discountinued the alto.
Hope this helps
