Re: important question about soprano repading..
'" 'If the original horn had pads with "domed" resonators, and the new pads have no resonators, the horn will play out of tune, since the size of the sound chamber has been slightly altered.' "
"This is not true. If a competent tech properly addresses the sax's tuning on re-assembly... What the dome changes is the effective opening of the tonehole. In general going from domes to flats or no reso usually requires the keys to be lowered slightly. Key word is usually. There are always exceptions."
As you noted, when the repair technician is competant, the horn would be readjusted to make up for the difference when going from domed resonators to no resonators (or flats).
However, in this case, the returned horn did not play in tune, and was subsequently found to suffer from some leaks. This being the case, it appears as if the technician did not even play the horn after the repad, or he would have discovered the leaks before returning the horn to the customer.
I did not mean to imply that a horn designed with domed resonators could not be made to play in tune without such resonators, just that a simple repad without attention to this detail could be a problem for the intonation of the horn.
Thank you for pointing out my omission.
