Regarding the value of a purple logo YAS-62 neck I recently found one at PM Woodwind for $175
Perfect condition. My situation was I got a great deal on a YAS-62 sax (not a purple logo but an early one with the J shaped key guard on the bell), but when it arrived it had a G1 neck. Not a bad neck but took some adjusting in the upper register. I was lucky finding an original early 62 neck and plays much better.What condition was it in? That's a great price.
