Get ready for mics coming at you in stereo (though not a stereo pair) as we check out the Shure PG27USB and the Shure PG42USB at the 2009 Winter NAMM Show. The PG27USB, one half of Shure's new team of large diaphragm condenser USB microphones, is built to mic just about anything that makes noise from peeps to bellows while the PG42USB, like most people who listen to radio, focuses on the vocals.
