James,

That would essentially mean that the bell (and the hole on the Fobes extension) to some extent is venting the throat tones.

It is easy to test. Remove the bell, play a G4 and let your left palm cover and uncover the bottom end of the lower joint. This has much more effect than the Fobes extension possibly could.

When I try it on my Bb, the pitch of the G4 does not move a cent. The tone character changes a little though. I suppose this could be the high-frequency overtones that don't get killed by open tone holes now get killed by my hand.

To simulate the effect of the Fobes extension more realistically, you could keep the bell on and flip the E3 cup with your left hand. I tried it and again, no effect on pitch but a slight difference in character.

I did find a way to affect the pitch of the G4 using the lower joint tone holes. I turn the lower joint to disable the bridge to the upper joint. Covering all lower joint tone holes does not change pitch. But covering the Bb3 and A3 tone holes brings the pitch *up* 5 cents or so. Quite interesting. Somehow I manage to shorten the G4 wave. This is however, closer to the G4 hole than the Fobes extension.
