Ok, a bunch of notes stopped playing and I traced the problem to the neck/mpc. Then I checked the neck and that seemed OK. I did the suck-pop with the mpc and it totally failed. So now its got to be the reed, ligature or mpc. It's not the reed. The weird thing is that if I re-adjust the reed, the suck pop works and so does the sax. Could this be the ligature? The mpc is a hard rubber Selmer S80 C*. The lig is one of those leather ones with a brass screw (about $30).
