I dont believe anything one uses to fill a soundboard crack will affect soundboard response perse. If the cracks have also loosened one or both edges from the ribs... then a given repair can have an effect and serve to stablize the situation. But cracks in themselves are acoustically rather insignificant. At least as far as anyone has been able to determine up to now. Cheers RicB Does epoxy repair change the soundboard response, then, or does it simply stabilize the board and ribs? Forgive me if I'm asking questions that I should already know the answer to, but I don't know. (I have lots of hypotheses built around what I've read and observed, but there are some big cracks in those, I'm sure. <g>) Thanks. Annie G.
