GT57 MULTIP ATTERN FET CONDENSER MICROPHONE
Perhaps GT’s most versatile large capsule mic with its ultra-thin 3 micron Gold evaporated Mylar diaphragm is uniquely hand built with our GT
exclusive Disk Resonator that naturally extends high frequencies to improve detail and depth,making it the perfect choice for both vocal and
instrument recordings.The 3 popular polar patterns give the recording engineer complete flexibility for all applications,and its exclusive FET Class A
electronics are so smooth and warm you might even think it’s a tube mic!
