| − | Guitars may be classified as being [[acoustic]] or [[electric]]. Acoustic guitars are usually made of wood, and produce sound based on the acoustics which resonate through the hollow chamber of the guitar. These guitars can be used in a live performance without amplification due to the resonance and volume the guitar chamber is capable of producing. | + | Guitars may be classified as being [[acoustic]], semi-acoustic or [[electric]]. Acoustic guitars are usually made of wood, and produce sound based on the acoustics which resonate through the hollow chamber of the guitar. These guitars can be used in a live performance without amplification due to the resonance and volume the guitar chamber is capable of producing. |
| − | Electric guitars are also made out of wood but are usually not crafted in a hollow-body structure to allow the strings to resonate into the chamber. These guitars usually have electromagnetic pickups installed which are led to an [[amplifier]] to produce the sound being played. | + | Semi-acoustic guitars are hollow-body acoustic guitars that have been equipped with an electromagnetic pickup so that they can be played either with or without amplification. |
