The V-200 employs a Carpenter-style, 1/4" output jack which mounts on the side of the instrument with chinrest-style hardware. When paired with an impedance-matching preamp, such as the Platinum Stage, Platinum Pro EQ or Powerjack, the full potential of the V-200 can be realized yielding full natural sound. The impedance-matching preamp is recommended, but not required. This Piezo-ceramic pickup is easy to install and requires no alteration to the instrument.
