It could be that the overall assembly is too flexible and the lack of string load at the strut lowers the impedance there too much. String load does raise impedance. Maybe too few  ribs, and/or not stiff enough. Is it the bridge that's causing the problem?        Phil_-Ron >>.Hey I know this true but why is it that the sustain and power is frequently so much better and not worse with the two notes on either side of a break where the bridge is not cut? I've thought just the opposite that perhaps the impedance was a little to high and the missing string pressure under the strut lowered the impedance just enough to cause the more free sound I'm refering to. Hey it's either that or Dales just hearing things.!</BLOCKQUOTE>        >>>>>>>Dale Erwin>>>>>>>. </HTML>
