Our smallest Pickup is designed to capture the bright frequency spectrum of the violin to give an amplified output as close to the acoustic sound as possible. The V2 Wilson Pickup consists of two piezo elements connected to a Switchcraft 121 extension jax is providing you the very best amplification for violin. The fine sound is focused and defined without feeding back at all levels. The output level is adjustable by rotating the pickup elements with the supplied adjusting key. The V2 Wilson Pickup is easily mounted directly into the bridge and the specific mounting position provides the natural acoustic sound from the violin. Special mounting tools are included with each set of Wilson V2 pickups.
