I have a YTS-82Z unlaquered, no high F#. It was one of the early "prototype" Z's, and was in Ronnie Laws' possession for a couple of years before I got it. It has brass resonators, and I am using the unlaquered G1 neck and a Ponzol 110S M2 Plus mouthepiece with a Plasticover 3. I am really enjoying this complete set-up. I hope you enjoy your new Z as much as I like mine.
When you get your horn, you should definately have your horn fully adjusted and checked out by a good tech for any problems, so that when you play it, you know the horn is doing what it's supposed to do. After that play it for awhile, and if you want anything tweaked for your preference, then bring it back to the tech that did the original "set-up", and have whatever you need taken care of.
The Yamaha "Custom" saxes are "set-up" at the factory in Japan. Before they are sent to the dealer, they are sent to a Yamaha "Custom Shop" in the U.S., and then they are gone through there, and "re-" "set-up." However, they still should be checked over again before a customer trials a horn, just to be certain everything is like it should be.
I am certain that many people who try out saxes don't realize that a horn in proper playing condition will outplay any sax that isn't. Any of the well known saxes, from modern to vintage, should be a decent playing horn........if properly set-up, of course.
