LR Baggs Anthem contains the internal Tru-Mic system along with the LR Baggs Element undersaddle pickup along with a soundhole mounted preamp. The LR Baggs Anthem is a revolutionary new type of microphone. Utilizing a proprietary noise canceling mic, the LR Baggs Anthem Tru-Mic eliminates any annoying honky or boxy qualities that have been previously associated with internal mic’ing, leaving the pure and natural sound of your guitar the way only a real mic is capable of doing.

Because the mic is positioned within a few millimeters of the
guitar top, it has very high gain before feedback. The mic housing
mounts easily to the bridge plate and the mic capsule hovers just 3 mm
above its surface to take advantage of the PZM or “boundary” effect.
The LR Baggs Tru-Mic technology picks up the sound of the vibrations of the
entire soundboard and makes the mic unusually free from placement
issues.
