Why yes, I suppose they do. And we hear from many holds that cracks in soundboards do nothing to the performance of the soundboard per se. We hear a lot of very specific claims from a lot of folks all over the place put in very authoritive language. One of the pieces of advice I have found most valuable given to me here some years ago was to not just swallow any of it, but to check things out on your own. First check I make is to see if a claim is based on real controlled observation or not... or whether its based on theoretical musing. Stephen Birkett said something to me this summer that sat very well with me. It more or less boiled down to... << if you cant take a picture of it... then you dont know really know for sure whether what you think is happening really is >> Cheers RicB Steinway bluntly says in their technical reference manual for technicians that compression ridges are not a problem and are a sign of a good board under ideal compression. I'll leave it at that as I don't want to catch the flames 8-) Andrew Anderson
