A semi-acoustic guitar or hollow-body electric is a type of electric guitar with both a sound box and one or more electric pickups. This is not the same as an electric acoustic guitar, which is an acoustic guitar with the addition of pickups or other means of amplification, either added by the manufacturer or the player.
Other semi-acoustic or acoustic electric instruments include basses and mandolins. These are similarly constructed to semi-acoustic guitars, and are used in the same ways and with the same limitations.
More often, the instrument is designed primarily to be used with an amplifier, and the sound box is used primarily to produce an amplified tone not obtainable with a solid body instrument.
Some are borderline between these two types. For example, some electric archtop guitars are physically and acoustically identical to models from the same company without pickups, but the electric versions are almost never seen in performance without an amplifier. So, although the instrument is demonstrably capable of use as an acoustic instrument, in practice this does not occur.
Some models have a fully hollow body (for instance the Gibson ES-175 and Epiphone Casino), others may have a solid center block running the length and depth of the body, called semi hollow body (for instance the Gibson ES-335). Semi-acoustics are capable of producing a fuller and richer tone than most solid-bodied electric guitars, but are prone to feedback when played through an amplifier. Because semi-acoustic guitars can be connected to an amplifier, they can be played at a much louder volume than simple acoustic models. They are favorites of big band guitarists and jazz players particularly.
Other instruments are borderline between semi-acoustic and solid body. For example, some Telecaster guitars have chambers built in to an otherwise solid body to enrich the sound. This type of instrument is often referred to as a semi-hollow guitar. Exactly where the line is to be drawn between a constructed sound box and a solid wooden body, whose construction also affects the sound according to many players, is not generally agreed.
Generally, hollow body electric guitars are lighter than a solid body guitar of comparative size because its body mass is reduced as a result of the addition of sound chambers. However, they face problems in high-gain amplification, as the sound chambers also induce unsavory feedback.
Some companies that have produced famous semi-acoustic guitars include: Gibson, Gretsch and Rickenbacker. A variety of manufacturers now produce semi-acoustic model guitars: D'Angelico, Epiphone, Ibanez, etc.
