There's probably a better forum for this, but I figure most soprano players will see it here anyway.
I sent Joe a recently acquired (used from Ebay) Missing Link that had some major issues, along with my beloved JodyJazz Classic. Joe's communication was fast and friendly, and his prices were good. I just got the pieces back yesterday (13-ish days round-trip, including a holiday weekend) and they play great! The JJ plays better than ever (less resistant, easier top-to-bottom), and the ML plays SO much better, nearly effortlessly! I actually can't decide which piece I like better.
If you need a soprano piece adjusted, definitely shoot Joe an email.
