OVERVIEW

A preamp designed to restore the beautiful acoustic sound of your guitar.

The D-TAR Mama Bear Digital Acoustic Guitar Preamp is your secret weapon for capturing and reproducing all of your acoustic guitar's presence and rich tone. Even the best acoustic guitars deliver an oversimplification of true acoustic tone complexity when amplified. The D-TAR Mama Bear Digital Acoustic Preamp solves this problem using what they've named AGE technology. Mama Bear takes your guitar into the digital realm, neutralizes the pickup, and then restores the natural body resonance. The result: now the finest acoustic guitars can sound like, well-themselves. Only louder.

D-TAR - Duncan/Turner Acoustic Research
Seymour Duncan and Rick Turner are two legends who spent years working with musicians, perfecting their tone. Seymour founded his self-named company in 1978 which has become well-known for its wide variety of guitar and bass pickups used by just about every name player from Billie Joe Armstrong to Angus Young. Rick co-founded Alembic, was president of Gibson Labs West Coast R&D Division, co-founded Highlander Musical Audio making piezo acoustic guitar pickups for Lindsay Buckingham, Ry Cooder, David Lindley, and Andy Summers, and runs his own Renaissance Guitars. Now Seymour and Rick are working together to create innovative products for acoustic musicians. Their D-TAR motto: "With respect to acoustic tone."
