[CAUT] Soundboard Weighting

[Greg Newell]

OK, Has anyone else read this? I scanned it and found in numerous locations
the word “adjacent” referring to either notes or strings. It describes
undesirable tonality differences, that attaching the weight (between roughly
50-200 grams) is supposed to fix. I thought that the purpose of the weight
(brass or otherwise) was to change the impedance of the system in a
generalized area i.e. the treble range as we are accustomed to using it, not
targeting to adjacent notes or strings. Am I missing something here?

you need to be a full member to see the illustrations....but the text is
revealing.

 

This might explain the weighting in the Baldwin 6000 (not 7000)....Concert
