I've had a question about this for a while. It seems most people would agree that woods all possess a different tonal qualities. I don't understand how the wood effects to tone itself. The pickups and amp take the string vibrations and convert them into an electrical signal that can be interpreted. Where does the wood come into that? Can wood effect the electrical signal, that seems unlikely? Does it effect how the strings physical moves when struck? In a similar vein of questioning, how does being a hollow body effect the tone of something that is, again, coming from the pickups?
