AD-3 Acoustic Instrument Processor

The BOSS AD-3 Acoustic Instrument Processor is a compact acoustic instrument processing pedal developed exclusively for gigging acoustic-electric guitarists. Its features and technical specifications include:

- Footswitchable Bi-Stereo chorus offers split-frequency processing (Low and High) for a natural, smooth chorus effect.
- Studio-quality Reverb provides clear, deep reverberation specially tuned for acoustic guitar.
- Newly developed "Bottom" and "Top" controls offer variable tonal shaping to eliminate "dry" sound from piezo pickups and add rich, resonant lows and brilliant highs.
- Special Guitar Amp output provides proper impedance and tonal balance for a great-sounding connection to a guitar amp.
- Stereo balanced outputs allow for direct connection to a PA.
- Dual Anti-Feedback function can be manually set to eliminate feedback or can be set to "Auto" mode via footpedal.
- Battery or AC-powered for maximum flexibility.

The AD-3 also offers an adjustable Input control for impedance-matching to a variety of acoustic-electric pickup types, and its Output section provides a choice between stereo balanced outputs for direct connection to a PA system or a dedicated Guitar Amp output for plugging into a guitar amplifier.
