Please forgive a "lurker" to this discussion. I have no expertise to contribute, but perhaps another reference that might prove thought-provoking. At PTG 2000, I received a sample CD of the Wapin bridge modification (excuse me if this is a well-known topic, or worse, controversial). The liner notes say essentially that if too much energy passes to the bridge from the strings, the system will distort, and so this system acts like a resistor, to match the impedance, if it were. Further descriptions at http://www.wapin.com/howitworks.htm and in their patent (there's a link to it on their home page, http://www.wapin.com). As a software engineer by trade, it seems to me that a model is proven by its practical applications. Ideally it should describe all existing behavior, and predict the outcome of future experiments. --Cy Shuster-- Rochester, MN
