Electric Guitar
There are many types of electric guitars, most of them with a solid body. Ir features a neck with frets and six strings.
A bit of history...
The electric guitar originated from the acoustic guitar, but has a higher sound power and the possibility to change several features of its tone electronically.
How does it work?
With the intention of making the sound of the acoustic guitar louder, pickups were added in order to take its sound to a guitar amplifier. Therefore, the electric guitar does not need a hollow body.
