Trumpet Guy needs to produce "his research."
I would not presume, as a saxophonist of 45 years and a teacher of 36 years, to tell him anything about trumpets, as the history of trumpets is both beyond my interest and expertise. But we here at SOTW have been studying and researching these horns for years through the empirical truth of observable existing instruments, which speak for themselves. We have nothing to prove; the saxophones have proved it for us, again and again.
"What we have here... is a failure to communicate." In other words, Trumpet Guy is one of those people who cannot admit defeat; one who cannot stand to be incorrect. As such, he is merely an irritant, and probably just as laughable in the trumpet world as he is here.
