L.R. Baggs has refined their Tru-Mic technology even further to offer a standalone, low profile, internally mounted microphone for steel string acoustic guitar. The mic easily mounts on the underside of the bridge plate with the signal routed through a barrel preamp/endpin jack. The signal is processed onboard to minimize feedback issues and maintain a sweet mic sound, even with shifting dynamics. There is also a presence control to optimize high-frequency response for your guitar, as well as a soundhole-mounted volume control. Professional installation recommended.
