Although not as commonly experienced, resonator guitars still have a special place, and their distinctive sound is still very popular. Resonator guitars have a quality of sound quite unlike other guitars, and this is achieved through the use of a resonator fitted at the top of the guitar, in the middle. This resonator is made of metal, and its incorporation into the design of the guitar is not unlike that of the banjo, and there is certainly some similarity of sound quality between the two instruments.
