What do you use a resonator guitar for?

A resonator guitar, also known as a Dobro or National guitar, is a type of guitar that uses a resonator cone to produce a unique and distinctive sound. The resonator cone is a metal cone that is mounted on the body of the guitar and is responsible for amplifying the sound of the strings. Resonator guitars are often used in country, blues, and folk music. They are also popular with slide guitar players, as the resonator cone can produce a sustain and clarity that is ideal for slide playing. Some resonator guitars also feature a "spider" bridge, which is a metal structure that supports the resonator cone and helps to create the instrument's unique sound. Resonator guitars are typically played with a slide, which is a metal or glass tube that is placed on the strings and used to slide up and down the neck of the guitar.
