Pramberger

[Greg Newell]

Ron,
         Mr. Pramberger gave a talk at a PTG Pittsburg chapter meeting a 
few years ago where I asked him about the ribs and how they crown the 
soundboard. He said, at the time, that the soundboard was rib crowned. I 
didn't keep his attention long enough to ask what the  crown radius was for 
any of the ribs specifically but they are crowned. Hope this helps. It was 
a long drive to Pittsburg but ultimately worth it, I think.
