An acoustic electric guitar’s finish is another name for the final coating that is applied to the surface of the instrument.
As its name implies, the pickguard is designed to help protect the body of the acoustic electric guitar from any wear-and-tear that would occur from strumming and picking at strings. It is located below the soundhole.
The neck is one of the more easily identifiable pieces of the acoustic electric guitar. This area is where the instrument is held, it houses the frets that enable players to play notes, and it obviously also displays the strings.
