VV-1 is the best choice for musicians craving the natural sound of their viol without a lot of setup. A wood-encased piezo sensor installs safely and securely into the eye of the instrument bridge with minimal modification. A 1/4" jack socket mounts to the viol bout with a cork-lined clamp. Clamp barrels are easily adjustable to precisely accommodate the nuanced build variances of both violins and violas. VV-1 employs a passive system, designed to work flawlessly with your favorite acoustic amplifier or colored via your preamp of preference.
