Digital Acoustic Guitar Preamp
For years, acoustic guitars have relied on pickups for
amplification. One problem: Even the best acoustic
guitars deliver an oversimplification of true acoustic
tone complexity when amplified. Using
something called AGE
tecnology,
D-TAR's Mama Bear takes your guitar
into the digital realm and restores the
natural body resonance. The result:
now the finest acoustic guitars can
sound like, well... themselves.
Only louder.
