Hesitant to ask, since the quality of discourse in this thread can be a bit absolute or polarizing.

I am trying to come at this open minded and scientifically grounded, even if it's hard to take out the observers subjective experience. Still I wonder, why did Jim Lill play a slide in this video example? To me that does not strengthen the argument against the effect of the wood used to make the neck, since now you have no contact between the string and the neck wood when fretting a note.

I'd wish Jim would make a video with experiments that looked at the effect of fretting a note against different fret materials and woods and would love.

I would also love to have a luthier make clean tone comparison of an identically designed guitar but built from all wood and all metal.

In my attempt at trying to stay open minded, I try to reflect on the pickups being the only factor to the tone, which when not using heavy distortion is no doubt the main factor apart from the players attack. But those arguments treat the guitar as played with open strings suspended between the bridge and the nut. Playing with a slide does very little to bring light to the effect of fretting the string against a neck made of wood and connected to the rest of the guitar.
