    Question to pose to you folks, albeit a stupid and likely overdiscussed one:


    Opening the throat, it is my understanding that it makes the high register tend to go sharp and can also make the low register sharp. Have any of you found this to be true? 'Tis just my stupid question for the day. :oops:

    my interpretaton is a little different - when someone say open the throat i think of it being relaxed like when you yawn. it should open as much or as litte as it needs too. I guess forcing it to open or close could do something strange...

    Sorry, I should have clarified, the topic at hand is far stupider than you think. I'm speaking of boring the throat out on a mouthpiece. I'm a noodlebrain, thanks for being patient.

    I don't the the correlation is that straight forward. An open throat is also going to be dependent on cup size, rim diameter, backbore. So many factors involved. A general idea is that an open throat give less resistance, but makes playing higher a bit more difficult.

    Vincent Bach was said to have made his mouthpieces with a smallish bore, figuring everyone would drill it out if they needed to. Interesting.

    The idea behind the 1930 invention of the Rudy Muck mouthpiece was a "chambered" throat. Small enough to give some reasonable resistance, but the chamber allowed for a good tone. Close to the idea of the double cup mouthpiece.

    So many combinations ... no wonder brass players can spend a small fortune on mouthpieces!

    duh - its in the mpc section - should have looked.... yes boring it out make is go flat upstairs and sharp downstairs...

    This is because if you drill the throat you have turned the taper into a cylinder shape.

    This is the one time dewalt is not your friend. This is one of the cheapest alterations you have have done to a mouthpiece by a professional. Send it off or risk ruining it.

    I have reamed the throats of several mouthpieces and have never had a problem with intonation. However, I will say that the largest I've ever reamed to is a 24, which is really not all that large.

    are they all bachs? - I remember reading that Vincent desinged them knowing people would open them up. he had a set of reamers in his pocket in case someone requested it when they meet him in person.
