Each pickup produces sound. The body is light. While it's perfectly possible to use it in a standard way by setting your preferred positions and creating sounds, as shown in the fourth image, it's not quite a "monster modification," but it's just a step away from that, allowing for a wide variety of sounds. Basically, pressing the green button makes the sound thicker. It maintains a balance just before it would look a bit cluttered, yet offers a rich variety of sounds through switch combinations for each position. If you enjoy the modified feel, I think this is a fun instrument.
