The LR Baggs Violin Pickup features a miniature vibration transducer cast right into the bridge. The transducer is designed to accept the tone-rich left/right movement of the bridge, reject feedback, eliminate scratchy nasal sounds, and trace the natural sound of the instrument. The LR Baggs Violin Pickup has set the standard since its inception over a decade ago, and it is the top choice of more top pros including Alison Krauss, Michael Doucet, Darol Anger, and Jean-Luc Ponty, than any other pickup. The pickup is a miniature vibration transducer cast directly into an Aubert no.7 Mirecourt maple bridge for maximum sensitivity and signal transfer. As an integral part of the bridge, it effortlessly captures the instrument's inherent dynamics. Furthermore, it's selective admittance pattern is aligned so that the signal is generated as the bridge moves in a left-right motion (in response to the string vibrations). The transducer also rejects any impulse directed to the plane of the bridge, minimizing annoying finger squeaks, body noise and feedback. The L.R. Baggs Violin Pickup also features unprecedentedly consistent performance, and will not affect the tone of your favorite violin. Each pickup is quality tested and carries a one year warranty.
