Re: [Harp-L] Covers

["John F. Potts" <hvyj@xxxxxxx>]

Frank,

As i recall, Dave didn't tell us which was which until after those  
who responded expressed opinions.  I think a couple of people  
obstinately asserted they heard no difference, but all of the others  
who participated did.  Dave can probably direct you to this topic in  
the archives. I don't know if he still has the sound samples posted  
somewhere.

FWIW, I suspect that  part of what appeals to some players who like  
MBs so much is the sound of the vented covers.  I do think vented  
covers have a somewhat more diffuse timbre than unvented covers.  The  
effect of other differences in cover design may be debatable or non- 
existent, but, IMHO,  the difference between vented and unvented  
covers is definitely audible.  I can't remember everyone who  
participated in Dave's survey, but I i did and i think Elizabeth  
(EGS1217) was another one of us that did. There were several others,  
but I don't recall who else.
