    This clip-on lavalier mic provides crisp, full-sounding voice pickup and excels as an instrument mic, especially for pickup of acoustic guitar. It offers excellent gain before feedback and suppression of background noise. An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off.
