There are two main guitar categories, namely electric and acoustic. This last category contains a large number of subcategories such as classical, flat-topped, steel string or flamenco guitars. Electric guitars can have hollow, solid or semi-hollow bodies and the vibration of the steel strings is converted into signals that are then fed to an amplifier.
