David Love davidlovepianos@comcast.net=20 David, Hmmmm? Older soundboards will be stiffer! The natural aging process of = lumber exemplifies this. If you live in an older home, try driving a = nail into the olde studs!!! Yeah, like w/o drilling a hole, first, = you'll be bending nails 24/7!!! However, you do bring up an interesting = point. My observation, on olde boards, is that the upper treble is very = "loud" and, with a decent bridge termination, is very clear. Why? = Because the board is stiffer. I think this is a very good reason to NOT = use hard hammers on an olde board! In years past, a lot of the OLDE = techs used to drop the entire scale, by 1/2 size! This approach, had = some validity, but, I persoanally think this is the wrong thing to do. = Of course, this practice came about, way before the Electronic Age of = easy accessability to an easy way of doing the formulae. Thank god for = the 'puter, in this case! I used to do scales on a TI! Talk about = tedious! One had to be really adamant about scales to persue that! (Let = alone, doing it with a Slide Rule. (you do remember those lovely = gadgets, don't you?<G>) As for the scaling, in and of itself, all we can do is to smooth out the = inconsistancies of the original factory screwups/design. And, hopefully, = not overstress the original intent of the structure design. At least, = this is my approach to scaling. If we are dealing with a new board, then = it's a whole different approach, IMO. Best Regards, Joe Garrett, R.P.T.
