    (such as a room or hall), the composition of the surface (a wall, for example) reflecting the sound, and so on. With the AD-3, these elements are digitally simu- lated to obtain the optimal reverb for the acoustic guitar.
  • Page 13: Adjusting The Bass Sound (Bottom)

    Adjusting the Bass Sound (Bottom) This knob adjusts the sound of the guitar’s sound box, or suppresses excess bass notes. 1. Adjust the Bottom knob. fig.10 Setting this more toward RICH accents the rich- ness of the sound-box reverberations, and setting it more toward SHARP suppresses the bands that interfere with vocals and the like, thus helping to prevent acoustic feedback (howling).
  • Page 14: Reducing Acoustic Feedback (Anti-Feedback)

    This features attenuates the sounds at the frequen- cy where acoustic feedback occurs, thus suppress- ing the acoustic feedback. The AD-3 has two types of built-in anti-feedback features. One sets the howling point with a control knob. The other automatically detects the howling point when you press the pedal.
  • Page 15: Switching On The Anti-Feedback Auto Function

    Switching On the Anti-feed- back Auto Function 1. Press the Anti-feedback Auto pedal. fig.14 The pedal indicator blinks while detection of the howling point is in progress, and lights up steadi- ly when detection ends. Switching off the power returns the pedal to NOTE its off state.
