Hi! I change my tenor some months ago. I used to have an old Conn (1922) and i bought a 2002 Reference 36. I got an issue. from the G (octave) to the E (palm key) there is a low buzz (is the low frequency of each note). I sent it to the luthier. He open up the pipe holes, open the key-work and recently I change my early babbit otto for a jazz model of phil barone (number 8). I can´t find a solution. I´m starting to think that is a neck issue. Somebody knows something about this?! I´ll really appreciate some help.
