The sound of the blues. The Shure Green Bullet Microphone started its journey back in 1949. And evolved to become the definitive harmonica mic. Famed for its unmistakable midrange punch and ability to cut right through the music. Just plug it in. And let rip. A mic like no other. The Shure 520DX adds subtle saturation to sound passing through it. In a pleasing musical way that has become integral to the harmonica sound we love. And its been specially shaped to fit neatly in your hands as you play. Along with die-cast metal casing and an immunity to moisture the Green Bullet is simply unrelenting. Its ready to handle years of hard touring.
