Question

Which part of acoustic guitar has the most impact on sound?

Answer 1

On an acoustic guitar, the construction of the guitar itself has the most impact on its sound. You hear the vibration of the soundboard, so what's important is the frequencies that are absorbed or reinforced by the way the body vibrates and the way the bridge transmits vibration from the string to the body.

You can put high-quality strings on a bad acoustic guitar, and it will still sound bad.

Answer 2

The body or the hollow part has the most impact on tne sound of the guitar
