I understand the principles of an acoustic instruments strings vibrating and and being amplified by the sound chamber, but how about on an electric. Ive been playing 35 years and i dont understand how a pickup actually works. I think that somehow the string vibrating in the magnetic field produces something that the pickup amplifies and turns into something else which then goes to the speaker and vibrates it somehow... Can someone explain this whole process in understandable terms for me. The main reason im curious is because i want to understand how body and neck wood choices affect tone. If an electric guitar uses electrical and magnetic forces to generate sound, where do the physical vibrations of the neck and body slab enter the equation???
