CONTACT PICKUP 'Unlike other bridge-mounted acoustic pickups that rely on string compression for their sound, the Element is designed to exactly reflect the sound of your movements as you play because it picks up strums. It has a heart with a flexible film sensor that picks up even the most delicate nuances. This minimalist construction reduces any influence and creates minimal space between the pickup and the guitar for the best possible fidelity. It fits any size guitar and captures all sensitivity and articulation. It has a Class A preamp pin and an easy-access volume control to mount on the soundhole of the guitar. It also includes a cover to prevent movement of the battery. It has an LF compression circuit that controls the low end and imitates the dynamic response of the guitar to improve realism. - Underbridge mounting - For 3/32'' and 1/8'' slots - Built-in LF compressor - Volume and tone control for mounting on the soundhole - For acoustic guitars with steel strings - Powered by a 9V battery - Long battery life. 1,000h'
