[Harp-L] Cellophane sealing

[Larry Sandy <slyou65@xxxxxxxxx>]

During a recent ultrasonic cleaning and customizing session I was considering 
air flow in harmonicas.  I temporarily sealed the whole back of a Special 20 
with cellophane tape and began comparing its playability with an unsealed model. 
 Of course many features of playing were lost but it seemed to me I could 
overblow and draw just a little easier with the sealed harp.  Has anyone used 
this set up in special playing situations?  

Curiously,
