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
