My friend thought this sland is designed push intentionally the sounboard (with the pression/ tension of the strings ) in a very small S shape , not so important than when the sounboard collapsed because of bridge roll i.e. This S shape would allow a more stable shape behind the bridge. My personal guess is it have something to do with the downbearing, better mechanical rendment, more pressure on the front pins on the bridge, or something like that. Or would the (curved) bridge be more rigid with this shape ? What do you think ?
