The middle D sometimes sounds suppressed and sometimes seems like the reed closes up. Took it to two repairman, one with a great reputation, but not not fixed. I'm beginning to think that the issue is with the left side bell keys resting against my leg - they are not physically touching my leg or pants due to the metal bars around the keys, but maybe the airflow is impeded. Also, the octave on the top of the sax tube, not the one on the neck, opens about 70% of the way. Anyone else have this issue? How was it fixed? I really like the horn but cannot use it on a job the way that it is. Thanks!
