[Harp-L] OB/OD harp setup

[Vergil Mueller <vcm2@xxxxxxxx>]

I'm somewhat of an OB beginner, and have recently been trying to 
incorporate more overblowing into my  playing. I have done fairly well 
with the 4 5 and 6 hole overblows, with just a slight modification of 
the reed gaps.  The hole 1 overblow and the 7, 9 and 10 overdraws are a 
bit more elusive, though.  Does anyone have some pointers on setting up 
harps for the low and high OB/ODs?  I mainly play Special 20s.  I have 
read the pointers on tenhole.com and the "myquill" harmonica reference 
site, but neither really speak to the specifics of setting up the low or 
high reeds.

Particularly, there are a lot of really high squeaks when I try to 
overdraw the high notes.  When I do get the overdraw, it's very airy and 
I feel like my head is going to implode.  I have read that using wax or 
nail polish in the corners where the reed connects to the comb helps 
reduce the squeeks, but I was wondering if there are other things you 
can do to make the compression better, to help the notes just pop right out.

Also, has anyone written a book of OB/OD exercises/techniques or does 
anyone know of any such websites?

Harpily,
Vergil
