Resonator Guitar

The resonator guitar uses one or more metal cones mounted inside its body to project sound more loudly than a standard flat-top acoustic guitar, which was the original motivation behind its design. It can be played in standard fretted style or held horizontally and played with a slide, a technique especially associated with blues and bluegrass dobro playing.

Origin and Background

Resonator guitars were patented in the late 1920s by the Dopyera brothers and the National String Instrument Corporation, developed to give acoustic guitars more volume before widespread electric amplification was available.
