B-Band is a manufacturer of high quality pickup systems for acoustic guitars, double basses and drums. All B-Band pickups use our proprietary patented electret film technology! B-Band pickups do not use common piezo material like most of their competitors. Piezo pickups tend to impart a sound of their own, often described as "quacky" or "plastic", B-Band transducers act in much the same way a condenser microphone does. This results in excellent reproduction of your acoustic instrument's unique voice. "Hear the Truth"™
