It's really interesting that an electric guitar's tone is affected by the type of wood used, the resonance of the body, etc. Magnetic pickups only "listen to" the strings, so those characteristics must be transmitted through the strings as well.

This means that the instrument is a system, wherein the plucking of the string causes the body to vibrate, which transfers a portion of that energy back into the string. I'm used to thinking of body resonance as a sound in its own right.

In an acoustic, the body resonance is a big part of the sound.

An electric seems like the string is acting as a microphonic membrane in a way. It both triggers the wiggling of the components *and* transmitting their resulting patterns.

I started thinking about this because I've never owned an electric with a resonance cavity before. It's weird how it really beefs up the sound, especially in the low notes, but also adds complexity and air to chords and picked single notes.
