This clip-on lavalier mic provides crisp, full-sounding voice pickup. It also excels as an instrument mic, especially for pickup of acoustic guitar. The wired configuration (AT831R) includes the AT8444 guitar mount. The mic is ideal for higher SPL applications, and offers excellent gain before feedback and suppression of background noise. Includes windscreen and clothing clip.
