It's easy for people to post anything they want to.

It's a bit harder for them to explain why what they're saying is true.

When you fret a note, nothing moves except the string between the fret and the bridge.

For that matter, people claim to hear sonic differences in fretboards. Some say it's the hardness of maple vs the softer rosewood or ebony. Some say Maple has more mass. Well, hmm....the string rings between the fret and the bridge, and never touches the fretboard (on the ringing section of the string), so how could the hardness matter? And the fretboard slice (on rosewood or ebony, or ever 2-piece capped maple necks) is so thin, is there really any way that the mass difference (if there is one) could matter enough to hear through an amp?

Guitar players are voodoo/mojo loving fools sometimes (and I'm absolutely not immune!). Most of it is just that: voodoo.
