God there are an awful lot of videos on the tube on this subject,
So I'm gonna bow out of this debate for my sanity, attached is a clip explaining the science behind the anti tone wood campaign, https://youtu.be/svmOQuNC1Uw
But what he did not explain or go into was the harmonic content of the wave he referred to as timbre, This[b] is[/b] the tone signature of the component parts Neck, body, bridge nut etc. Harmonics give us a reference signature from which we learn and recognise different sounds. So basically my point is -
If you can tell the difference of a note - e.g "C" played on a piano and that same note (frequency/pitch) played on a trumpet and clarinet, Bass guitar. We can all Identify all those instruments blind, So it is not just wavelength and frequency, It is the harmonic information that is telling the brain this is a clarinet, it may be harder to identify a note played on an Alder bass with maple neck made in the 50's,60's,70's,80's,90's, etc but we could differentiate the difference, good bad and indifferent.
Could a cheap £200 P bass copy ever bark and burp like a neck through Warwick thumb made of Wenge and bubinga ???
