a_arnold -> Chica and the use of light-weight bridges (Oct. 12 2007 20:35:57)

Anybody have any comments on the Nov issue of "Vintage Guitar" article on Manuel de la Chica? Lots of interesting luthiery stuff in there on one of the greats of the Granada school of building.

Brune (the author) says he stood head and shoulders above his contemporaries. I didn't realize that was a generally accepted opinion.

My question to you guys:

Apparently Chica used African mahogany by preference (rather than ebony) for his bridges. Brune says Chica used it because it is lighter but, unfortunately, much softer so the bridge holes wear out and the bridges are often replaced with ebony, which changes the sound radically.

What effect does the difference in density of the bridge have on sound? Is it just that a light bridge will accelerate faster in response to string vibration?

Have any of you experimented with lighter bridge wood?

I can confirm that my '61 de la Chica has a mahogany bridge. With the staining, it looks more like dark walnut than ebony.

I don't know how much that affects the sound, but it is loud with quick response.

Hi

I think that light weight bridges are very important for a good guitar, not only for flamencos. I have recently made a test with a ready braced soundboard. I knoked the soundboard to get the top resonance and it sounded at B. After having sticked a rio rosewood bridge on it witt double sided tape, the pitch dropped to an F# and the soundboard did not respond easily due to the mass of the bridge that has to be put in motion.

My conclusion was, that the bridge was too heavy and i should avoid using such heavy bridges on flamencos.
