Woody, one dimensional as in emphasizing treble?

I use this brace-funny no one asked the demensions!
As I posted it's part of a plan to get the center of the top stiff.
Making the center stiff and the edges flexible is the sound I like .
Plus it helps with the loudness of the guitar & responce!
The guitars have better sustain also .
I do not make Dreads-just small steels .

When I say "one dimensional" I mean........very few overtones, quick decay on bass, but kinda naisley, with too much sustain on the treble.

I'm not saying these braces cause this. I'm saying a top that's too stiff across the grain causes this, or can cause this.

Since I require some physical rationale to be offered before I incorporate a change, I have not touched this one, which offers "magic."

Howard as you know there is NO magic in guitarmaking.
The idea is to keep the area around the bridge stiff first!
Then work the rest of the top for air pumping!

I HATE the Martin bridge hump !
I've fixed more Martins with a swollen top then any other makers guitars!
Plus it slows down the time it takes the guitar to respond by being so flexible .OR the guitar responds but decays fast !
That's for factory guitars of course!

See you in Woodstock in a few weeks !

I also would be interested in a physical explanation of why this brace would do anything. My own intuition is that jammed up against the bridge plate, it would do little more than what the bridge plate already does in terms of stiffening the top. Moved away from the bridge plate a little and made so that it extends more out the the sides, and I could intuitively see that it would add something. Of course, my intuition could be wrong - some of the neatest things in physics are totally counter-intuitive but true.

my totaly amateurish, wild ,out side, ( considering there is no magic in luthiery) guess would be it minimizes the cross di-pole mode action......
