Re: [Harp-L] opened up cover plates?

[Joseph Leone <3n037@xxxxxxxxxxx>]

I have always felt that closed up backs to covers bounce the sound around and soften it, while wide open covers brighten it. Am I wrong? If I am then what is the purpose of cupping....and UNcupping? Someone? Anyone?

Plastic covers like on the Hohner Piedmont and gum ball jars would solve this. Maybe also chrome or stainless steel covers. And the wood covers -- which have apparently disappeared from the market.
