Oskar and Overblows?

[Jcangehr@xxxxxxx]

Hi everyone,

I am new to the list, and very much appreciate the discussions that appear 
here--stimulating and helpful.

In all of this talk about the XB-40, I seem to remember a recent post that 
mentioned parenthetically that overblows are "impossible" on Lee Oskar 
diatonics.  How true is this?  I use LO's, and have the hang of the 7 OB pretty well, 
but not the 9.  With practice, can it be done, or are other harps simply much 
better for OB's?

Thank you,
Jim A.
