La large bore, la n.3 è a mio giudizio quella che ha il suono più bello di tutte, ed è per questo che costa più del doppio di una M o ML. Chris botti usa le n.3
Le misure della martin erano:
a small bore, #1 (0.445)
medium bore #2 (0.451), sometimes designated with a star above the serial number
extra large bore #3 (0.468).
Wallace Roney describes a couple of Committees from Miles Davis' collection:
I have two of Miles Davis's horns of these vintages. One is an all copper Committee, black and copper color with a medium bore that progresses to a large bore. I also have a blue one that is a RMC Martin. It starts at . 342 in the leadpipe, at the end of the leadpipe, is . 453, the tuning slide, tapers to 460. The end of the tuning tube, is 462, and through the valves, it's 468 and the bell-tail is . 474. This is an amazing horn--it's all brass, but the inner slides are all nickel/silver. I've been trying to find another horn like that all my life, but can't seem to find one, because I do not take this horn out, although I've used it on some of my best recordings. Although both horns play magnificently, I've been trying to find one just like this particular Martin Committee. I've also seen a photo of Dizzy Gillespie playing this same vintage only with a solid silver bell, and no it wasn't his King trumpet.
Although primarily thought of as a jazz trumpet, there were a number of orchestral players and recitalists, including Armando Ghitalla, who also played the Committee, especially prior to the Bach C trumpet dominance of recent times.
