Re: trade alto yamaha z and yamaha 62 tenor for Mark 6 tenor?
I wouldn't do it. Then you'll only have a tenor. The 62II plays almost as good as the Z, and the Z is a perfectly good horn. What is the serial number or year of the mark VI?
Don't get me wrong, my '56 Mark VI is my favorite horn, but sometimes people take to much stock in the title "Mark VI".
