Fishman Aura: The Fishman Aura Dreadnought Pedal uses proprietary Acoustic Imaging Technology to transform the often-harsh sound of an undersaddle piezo pickup into a rich, studio-quality tone, as if recorded by high-end microphones on a premium dreadnought guitar. It works by blending your pickup's signal with "Images" (digital recreations of mic'd guitar sounds) to add natural resonance, depth, and clarity, making your live or recorded amplified dreadnought sound full and three-dimensional. Key features include volume, blend, and image select controls, a phase switch for feedback, and robust 24-bit A/D D/A conversion for pristine sound.
