Element Active SystemAdvanced Undersaddle Pickup With Unrivaled Dynamic RangeUnlike typical undersaddle acoustic guitar pickups that are dependent on string compression for their sound, the Element was engineered to mirror the soundboards actual movement as you play. At the heart of the pickup, a flexible film sensor only 2 thousandths of an inch thick picks up the guitars most delicate nuances. Tracking the motion of the top rather than a direct string attack suppresses quack caused by compression and unlocks the Elements unrivaled dynamic range. The pickups minimalist construction lessens any influence on the acoustic properties and creates an intimate coupling between the pickup and guitar for the highest fidelity possible.Element Active System VTC(Volume and Tone Control)The EAS-VTC builds on the strengths of the EAS With the addition of a treble tone control and a special low frequency compression circuit. The LF compressor tames low end thump and mimics the actual dynamic response of the guitar for enhanced realism.FEATURES:All-discrete endpin preampPre-attached Element pickupFits both 3/32 and 1/8 saddle slotsBuilt-in LF compressorSoundhole mounted volume and tone controlBattery type: Single 9VBattery life: 1,000 hrsOptions:STEEL STRING:ELEMENT ACTIVE SYSTEMELEMENT ACTIVE SYSTEM VTCSTAGEPRO ELEMENTNYLON STRING:ELEMENT ACTIVE SYSTEM CLASSICALELEMENT ACTIVE SYSTEM VTC-NDownload Element Active System Series GuidesElement User GuideElement Installation ManualPLEASE NOTE:Baggs products must be installed by an authorized Baggs dealer to qualify for warranty coverage.
