Designed to be used with electro acoustic guitars, to eliminate thin, trebly signals and feedback, often produced by piezo and magnetic pick ups. The AD 3 has advanced, onboard tone controls, named "Bottom" and "Top." Far more effective than simple EQ knobs, these controls incorporate sophisticated filters which work differently when boosted and cut. The Top knob boosts high-end brilliance or can be used to eliminate the thin, dry sound characteristic of most piezo and magnetic pickups, making your tone more natural. The Bottom knob tunes the low frequencies to add the desired amount of rich body resonance. The AD3 runs a classy 2x2 stereo chorus adding just the right amount of sparkle to your sound. Real depth is provided by the included reverb.
