It’s got characteristic, metallic sound, a hard attck and soft sustain, a bit like a piano. It was designed in a pre electric and amplifier period. It’s got a kind of a speker conus that makes the instrument louder in an orchestra. It’s found its way in the blues, I love the sound in Romeo and Juliet. https://www.youtube.com/watch?v=nvLzmxOjqVE #national #deltablues #direstraits #dobro #resonator
