Here's a description of the Lyric and Anthem from LR Baggs to help decide which works for you.
We created the Lyric to represent a studio mic’d recording of an acoustic guitar that is engineered for live performances. Employing a microphone as the stand alone source reproduces the most natural amplified sound that we offer in our line of products. The Lyric has all the benefits of a well mic’d guitar while minimizing and/or eliminating many of the obstacles that plague microphones in a live situation. Think of the Lyric as a studio microphone that becomes an integral part of your guitar anywhere you choose to plug in, studio or stage.
The Anthem delivers many of the benefits of a studio mic’d guitar for live performance with the added punch of an undersaddle pickup. The Anthem uses the microphone to cover most of the guitar’s frequency range for a natural sound while providing a bigger than life sound on the fundamental range with the Element pickup. The pickup also adds a higher level of stability for high SPL performance situations. This system is great for a customer that wants to hear the characteristics of their guitar, but deliver an even bigger sound when playing live.
