At the heart of every NS electric violin is the Polar ™ Pickup System. Sensor and bridge geometry are integrated to translate every nuance to the amplifier and speaker system. The big, bold, and brilliant tone looks to the future, yet the sonic ingredients of the acoustic violin are present and can be tamed to become traditional in character. The Polar pickup has the unique ability to analyze the direction of string vibration to enhance the bowed response and to facilitate bow technique. The unusually powerful piezo crystals do not require on-board power, for maintenance-free performance without the hassle of batteries.
