I'm choking the column of air to get the bend, and tone does change
(suffer). So, how do you do those low bends without messing up your tone?
Peace and music,

The best advice I found when learning to bend the low holes is that you have
to draw from and feel it around your belly button. If you don't feel your
belly button when you draw on the low holes you aren't doing it right.
Once I learned to do this, I relearned all my bends using variations of this
technique. It became much less a mouth thing and more of a "drawing" thing.
