The Boss AD-2 Acoustic Preamp analyzes an acoustic guitar’s signal in real time and processes it to re-create natural acoustic tone while allowing players to achieve tonal balance for any style of playing. Its Ambience effect adjusts reverb to complement each instrument’s voice, while its reverb is optimized for acoustic-guitar performance. Other features include two independent outputs, low-frequency feedback reduction, notch filter, and footswitch mute. To learn more, visit www.boss.info/us.
