Resonator
This type of guitar is similar to the steel-top guitar, but the steel in the middle of the soundboard is used to amplify the sound from the vibration of the guitar strings to produce a very thin and distinct sound. These guitars are generally used when playing the blues. There are also variations of the resonator guitar: the square-neck resonator guitar is played on the lap like a piano or organ; and the round neck resonator guitar is played like a common guitar. Resonator guitars work very well with glass or metal slides.
