Now, also consider how your pickups are mounted. If your guitar was made of a material that did not vibrate at all when struck, you'd never hear a sound at all (except maybe the standard 60-cycle hum), but guitars are made of wood, carbon fiber, or other materials that do have the ability to vibrate, some more than others. Are you still convinced you can hear the sound? Again, you might actually be and here's why. Now, let's deaden the strings by placing a cloth below the strings and on top of the pickups, thick enough that there's a good bit of pressure on the strings and you're pretty confident the strings aren't going to move, and do the same rapping. If you just tap on the guitar with a knuckle while adjusting the volume you might convince yourself that you hear the rapping in the headphones. Also, don't strum, we don't want to deafen anyone. It's just that physics on paper is simplified and much cleaner than reality and, in reality, things are always moving.Īs an experiment, you can plug in your guitar, max out the volume on your guitar and headphones on the cleanest setting you can find on your amp with no effects of any kind. Physics is generally right in this case in that if the pickups don't move and the strings don't move, there is no output. I'm here to say that both camps are slightly correct and slightly incorrect and it's all about construction (and physics). The other group are staunch adherents to physics and they know that the only sound an electric guitar pickup can make is that which is generated by the change in electrical output as a result of the changing magnetic fields produced by ferrous strings moving in said magnetic field. One group will adamantly adhere to the idea that guitars are magical machines capable of defying physics as we know it and that each is unique and different wherein only one can make the very special sounds it makes.
So this is an age-old question with people firmly planted in both camps.
