Post subject:  Building for a 'bright' tone

What are the contributing factors to obtain a 'bright' tone? I'm building a 6 string Dreadnaught, Carpathian Spruce top, Koa body,Mahogany neck,Ebony F/B and bridge. Standard Martin X-brace and body depth. Does scalloping affect the tone? Would a smaller soundhole be better? Any information will be greatly appreciated. Thank you.

Actually a smaller soundhole lowers the resonant frequency. If anything you want a bigger soundhole. You could close the splay of the X a little and that will help give you a brighter tone. Stiffen up the top a bit. Those are a few variables that would help you go brighter.

Also I believe notching the tonebars and finger braces into the x-braces helps. Rosewood for the bridgeplate?.

I would say Maple for the bridgeplate ? for a brighter tone. rosewood would make it basier.
Do check out the "Tony Rice" model by Santa Crus its a larger soundhole to enhance brightness and tone.

I find that 'well tuned' tops, in the sense that the 'free' plate modes have better shapes, or the tap tones are clearer and better defined in pitch, tend to give a 'brighter' or 'clearer' tone. Everybody uses the terms a little bit differently, of course.

A larger hole, and shallower box, will tend toward a 'brighter' tone.

Keep the bridge light.
