The GM 9 is a 9" gooseneck microphone for a dobro or archtop guitar. This gaggle of gooseneck (geeseneck?) microphones are designed to mount inside acoustic instruments. [. . . ] The scale drawings to the right are one-half actual size. Microphone Placement The black face of the mic is active, the lighter face is passive. Position the microphone approximately ¼" beneath the soundboard near the treble side of the sound hole, with the active black face of the microphone towards the interior of the instrument (approximately towards the chest of the player in a guitar). Rotating the active face of the mic towards the back of the instrument often tends to reduce excessive bass response. You are encouraged to experiment with positioning the mic until the best combination of tone and volume is produced. Like any microphone, the GM can feedback if not properly aimed relative to loudspeaker volume. The GM is a low impedance microphone intended for use with the Rane AP 13, which contain graphic equalizers to help minimize feedback as well as provide optimum tone and balance. Also see Rane Note 131, "Microphone Options for the AP 13 Acoustic Preamp. " GM 5 GM 9 GM 16 GM 17 GM 5/9/16/1 7 GOOSENECK MICROPHONES GM 5 and GM 9 Installation 1.

The punch mark on the jack face indicates the active face of the microphone, and should be directed toward the rear of the instrument.
