I have seen the phenomenon of two/three strings being "flatter" then each, individually. And, I accept Dr. Sanderson's explanation of the reason for the effect, more or less. However, I have also seen a reverse phenomenon of the unison being "sharper" then the individual strings! Would someone like to advance a theory on this???? Best Regards, Joe Garrett, RPT, (Oregon) I'm never lost, because everyone is telling me where to go. <G>
