"It's almost never the crack in the soundboard that buzzes.  The buzz is usually between the board and the ribs that often separate near the crack.  Filling the crack with shims is largely cosmetic.  It's most important to get the board and the ribs glued back together.  This can be done without restringing.  I made some clamps for this purpose back in the day.  This unit is similar.  Only requires a very small hole through the board.  I used 12 gauge piano wire for mine, which is .025\"   "
