The AT8492UL Universal Clip-on Mounting System (9" Gooseneck) is designed to work with the ATM350a Cardioid Condenser Instrument Microphone. The system includes an AT8491U Universal Clip-on Mount and AT8490L 9" Gooseneck. The rugged, metal clip-on mount features rubber-lined clamping jaws with a locking screw that allow the mount to be safely and securely attached to an instrument or other surface. The strong, flexible gooseneck, which is held securely in the mount's socket by a locking screw, lets you position the mic where you want it and holds it there, no matter how much you move your instrument as you play.
