The cardiod microphone is mounted at the end of a 5" gooseneck. The unit clips to the edge of the soundhole. Mic head may be positioned inside the guitar or outside, as the player deems most satisfactory. Mic comes with volume control built into the battery box containing the 1/4" output jack. The unit is powered by 1 AA battery (battery life ~1 year). High quality low impedance (10,000 ohm) output signal. Frequency response of 100-15000 Hz.
For maximum performance, we suggest using a special Low Impedance Miniflex Cable (1/4" male phone plug to XLR 3-pin male plug). see below
