JZ BT301 mic is unusually shaped cardoid, mid-sized capsule microphone which gives great results in almost any application it is used. BT301 is the ideal for strummed string instruments, upright piano, cello, contrabass, violin, hand percussion and similar chores, finding its place any higher end mic locker.
