Does a guitar/bass body resonate differently when played in free air, as opposed to being strapped to the player..? What effect, if any, does the close proximity of the player have on any resonance..? Does the instrument sound different when played on a stand, or hung up in a shop, compared to on stage..? I would suggest that any acoustic effect of an electric instrument is so negligeable as to be beyond 'normal' human hearing. It may (note the 'may'...) be possible, in laboratory conditions, to detect something, but even admitting this, I don't think that this has any effect in a band, or recording, context, and is therefore a discussion for discussion's sake. Why not; it's of academic interest, but of little (read 'no'...) real-world value.
