First comes the classical guitar that is used for classic music tines. It is a precursor of a modern acoustic and electric guitar and contains strings made of nylon or gut. The second type is known as an acoustic guitar that is the most common and widely used type of guitar. The electric guitar is another famous type of guitar used in modern music. Unlike other types, this guitar needs an external amplification to be heard at a typical performance volume. This type of guitar uses more pickups to convert the vibrations of its strings into electric signals that are later reproduced as sound by loudspeakers.
