Getting Ready to Play Connections Connect your guitar and amp to the AD-3 as shown below. fig.2 Electric Acoustic Guitar Guitar Amplifier If you’re using a guitar amp, connect the OUTPUT R jack to the guitar amp and set the OUTPUT SELECT switch to G.AMP.
A brief interval (a few seconds) after power-up is required before the unit will operate normally. The peak indicator blinks for a few seconds, then you can use the AD-3 for playing. When running off batteries, the AD-3 won’t NOTE switch on unless there’s something plugged...
Chorus can be applied simultaneously to both bass and treble ranges in both left and right channels. You use the Chorus pedal on the AD-3 to toggle the chorus effects on and off. 1. Press the Chorus pedal.
(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.
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).
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.
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.
Appendices Troubleshooting If there is no sound, or if you think that the AD-3 may be malfunctioning, please first go through the follow- ing checkpoints. If after these checkpoints the prob- lem is still unresolved, consult your nearest Roland service center or authorized Roland distributor.
