| Feature | Benefit |
| 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. |

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. The revolutionary Mama Bear Acoustic Guitar Preamp takes your guitar into the digital realm, neutralizes the pickup, and then restores the natural body resonance.
In practical terms, the Mama Bear reduces to the point of non-existence the obnoxious attack transients (commonly called quack) produced by virtually all piezo pickups, and restores the complex natural sound of acoustic guitars. The amplified sound of the guitar is virtually indistinguishable from a well-recorded guitar in a studio -- but louder.
