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.
JZ BT301 is a perfect microphone for serious acoustic applications. Its GDC3 capsule provides the user with clear, powerful capture of most arco and plucked string instruments, amplified or naturally. Its clever body shape ensures minimal rear axis interference to the cardiod polar response
Michael Wagener (Metallica, Queen, Ozzy Ozbourne, Alice Cooper)
"I tried the combination of a BT201 and BT301 on acoustic guitar and it was the best sound I’ve heard from any new microphone."
