What is a resonator guitar?

A resonator guitar is a type of acoustic guitar that has one or more metal cones, usually made of aluminum or brass, set inside the body of the guitar. These cones act as resonators, amplifying the sound produced by the strings and creating a unique and distinctive tone.

Resonator guitars are often used in blues, country, and bluegrass music due to their loud and vibrant sound. They are also popular in Hawaiian music, where they are known as "dobros."

There are three main types of resonator guitars: the single-cone, the tri-cone, and the biscuit bridge. Each type has a slightly different sound and resonance.

Resonator guitars are often played lap-style, with a metal or glass slide, although they can also be played in a traditional upright position.

Overall, resonator guitars are known for their rich, metallic tone and are a popular choice for players looking for a unique and powerful sound.
