John what are you using to measure back pressure on the smaller to bigger tubes ? You really have me curious ! Also how do you know if there is any back pressure ? What does back pressure do if anything ? I know for a fact that a properly made reed does all the note changes so back pressure has nothing to do with note changes or as some call it (Breaking over a reed).
Can you please clear this all up for all of us wondering ?
Thanks

How do you measure your reeds over your competitors? Quality of sounds you produce and how easy you can produce them. Same with back pressure of a grunt tube.
Cover the exhaust port of your tub. Now blow into the intake port. The force you feel is back pressure.
If you need further explanation, here\'s a definition from a major call manufacturer.
Backpressure is a built in resistance in a call?s airflow. Backpressure affects the call?s sound when air is put into a call with minimal effort. It helps control a call much easier, while trying to make several different sounds. However, if you try and put too much air too fast into one of these calls, the call will break or squeak relatively easy. A call with little to no backpressure has to be driven all the way, but you will be able to push this call faster and harder, while calling.
Hope this helps Travis.
