A great Lavalier that also excels for miking acoustic guitars.

Audio Technica AT831B

The Unipoint is the first and still the best miniature condenser installed-sound microphones on the market. The AT831b is a clip-on lavalier mic that excels in acoustic guitar applications. It is essentially the same mic as the AT831R the differences being that the AT831b has both battery and phantom power, and a 6' cable.

Consumer Alert:

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
