---------------------- multipart/alternative attachment Ron, Barbara Although I'm not a compression crowned soundboard builder I have built many boards with many kinds of spruce & grain oreintations. Even pressing ribs on at 5.5 to 6.% compression still exsist in the panel. If I'm sending a board to the desert it gets dried a bit more. If the Bay area less is fine. My preference for tight grain Sitka has come after hearing many of my own boards. Tighter grains are of course mean harder & denser thus heavier wood. No surprise there. Exactly how that impacts the clarity of the sound is no doubt impedance related but beyond that it comes down to I like what I hear from this kind of tight grain, in the type of boards I build here. A Powerful clear dark sound with good balance. NO, it is not magic wood but it does have a bearing IMO. ...along with so many things. With this much soft spring wood in the Seiler board I suspect it will lend itself to more reactive movements with humidity swings especially or more so if the Seiler board is compression crowned & that can mean more tuning in-stability & the possibility for pre- mature or moisture induced cellular crushing. Just my 2 cents Dale WOW on a different subject. Is the entire soundboard panel constructed > with spruce that is about 8 grains an inch? What's up with that? > If so Holy Cats!! > Dale And just why would that be a problem? Ron N ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
