O aye
   The reason I started thinkin along these lines...a mate took a belt sander to an old Yamaha flat top.   Yup - a bloody belt sander!!

       He must've thinned out the top to absolute minimum, by accident!! He "finished " it with Black Bison wax (bees?) and now it sounds bloody wonderful and looks very bloody wonderful.....   Hmmm...One thing on a flat top...arch mando....dunno yet!!
