Well sarcasm and aside, and back to objective reality (ya I know no fun )
The article clearly states "
Our goal is to optimize the sound of your music by becoming the Preeminent Authority on Acoustic Sound."
Which is a pretty good goal as far as "goals" go IMO .... not sure I would want the goal of my guitar builder to be "
I want to have just enough knowledge of acoustic sound , to be mediocre" .....oops sarcasm
And to clarify "absence of evidence is not evidence of absence"
In point of fact what the chart actually shows is that Brazilian Rosewood has a strong bass response,,,, which virtually every good luthier understands
juss sayin'
