What is the purpose of guitar neck binding and how does it enhance the overall aesthetics and durability of the instrument?

The purpose of guitar neck binding is to protect the edges of the fretboard and add a decorative touch to the instrument. It enhances the overall aesthetics by providing a clean and polished look to the neck. Additionally, the binding helps to increase the durability of the guitar by preventing moisture and dirt from seeping into the wood, which can lead to warping or damage over time.
