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™ technology, the D-TAR 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.
Note! This preamp includes a standard 110 volt U.S. AC-AC power adapter. We can exchange this for a 220-240 volt adapter with the correct plug configuration for your country on request. Please call for details.
- 16 Position Input Source Selector - Provides 16 different digital filter choices to neutralize the
sound of your pickup so the AGE technology can go to work
- 16 Position Target Instrument Switch - AGE technology provides 16 amazing guitar sounds emulated from
16 amazing guitars, from parlors to super jumbos. Allows you to dial up the
guitar that matches your guitar's body shape, or emulate other shapes
- Input gain control with red Overload LED - Avoids overload distortion and allows minimization of noise
when different pickups are used
- Bypass switch with LED indicator when in bypass mode - Hard-wire bypass to allow comparison of
processed versus unprocessed sounds. LED alerts user when in bypass mode
- Output level control -
Gain match to next stage for best S/N performance
- Balanced XLR output - For
studio use with balanced-input mixing boards
- Hi-Z input stage - Works
with Piezo pickups, great stand-alone preamp
- Chassis compatible with Equinox and Solstice - Micro-rack system or two units in full rack mount
- +/- 12 volt supply for analog stages - Outstanding headroom performance
- Wet/Dry Blend Control -
Allows "In Between" amounts of processing
- Ground lift switch - For
studio use with balanced-input mixing boards
- Phase switch - Allows
reduction of feedback
- Mute switch - For quiet guitar tuning or elimination of live connection noises
