Nah, all that sounds reasonable. It was the tone from the neck or body part that sounded like voodoo. But when I say voodoo I partially mean I don't believe all that much in it, but I also mean that I don't fully understand it all.
The difference in tone is real, for sure, but I don't know that it's neck- or body- specific. I'm more inclined to believe that a neck-through will sound different because the body and neck are made from the same materials and therefore there's a continuance and resonance possible.
Set necks and bolt-ons have differences, too, but I think they're not so greatly different. Compared to a neck-through, they both have a 'break' in continuity at the joint, which is either negligible or noticeable depending on your ears, the materials, and how tight the connection/construction is. For example, a mahogany neck bolted or glued to a mahogany body (particularly, from the same piece of wood!) will likely have more 'continuity' than a maple neck bolted onto a mahogany body. Any neck poorly glued into an imperfect neck mortise will sound different than the 'same' neck bolted into a perfect pocket.
In any case, I'm not one to rip you apart for anything, I'm just another numptie.
