Many of you may have seen this insanely long and silly debate on SOTW, of the same name. Toby and I, amicably continued this discussion privately and eventually came to an agreement. My premise was, that 2mm thick (1.7.mm mean) Maestro/Noyek style resonators, displace enough of the tone hole chimney volume to noticably affect the acoustic design, and therefore the tone quality and response of the instrument, by altering the pitches of the harmonics which generate the tone. Toby claimed that the phenomena of Mode Locking. would insure that any detuned harmonic would be pulled back into an integral relationship with the fundamental, and there would be no noticeable effects. Toby later conceded, that Mode Locking does not actually work that way, that de-tuned harmonic resonances affect both the amplitude relationships of the resonances forming the note (it's tone color and it's response) and the actual pitch center at which the note stabilizes. Compression anti-nodes extend all the way into the far crevasses of the tone hole in it's vicinity, while the acoustic flow enters the tone hole chimney 10% of the diameter of the tone hole. So for a tone hole 20mm in diameter, the acoustic flow enters the chimney up to 2mm. If the tone hole chimneys on a saxophone are 2.5mm high, and it has 2mm thick resonators installed, then the acoustic flow will be changed at every tone hole over 5mm in diameter - almost every tone hole on any sized saxophone. The larger the tone hole, the more the effect. Just what the effects will be for any horn will vary, according to the original acousitcal alignment of the instrument. I think it would be safe to say, that if you really liked the tone and response of your horn in it's non-Maestroed state, that you would be silly to try to fix what already worked by changing everything. If you want to accentuate those qualities, to an point, oversized resonators of the original design that were on your horn, will give you more of the same thing that you like. If, on the other hand, you are not quite happy with the sound and response of your horn, then there is a chance that you might find the Maestro redesign of your air column an improvement.
