AD-3
Acoustic Instrument Processor
AD-3: Acoustic Instrument Processor
Features
Developed for stage and studio use, the AD-3 gives acoustic-electric guitarists a warmer, richer sound thanks to its Tone shaping controls specially tailored for acoustic-electric guitars, high-quality Reverb and chorus, as well as a built-in Feedback eliminator. Quite simply, this compact pedal is an acoustic musician's best friend.
- Compact acoustic instrument processing pedal developed exclusively for acoustic-electric guitarists
- Footswitchable Bi-Stereo chorus offers split-frequency processing (Low and High) for 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 connection to a guitar amp
- Stereo balanced outputs allow for direct connection to PA
- Automatic Feedback Eliminator can be manually set to eliminate feedback or can be set to "Auto" mode via footpedal
- Battery or AC-powered for maximum flexibility
