NS Design CR4 4-String Electric Viola, Amber The NS Design CR4 Electric 4-String Viola With Amber Finish features the Polar bridge-mounted piezo pickup system. The Polar pickups can sense either vertical or lateral string vibration. Set in the vertical mode, plucked notes are remarkably even and sustained. In the lateral mode, the pickup has unparalleled sensitivity in the direction of the bow, with more attack when plucked. Attack and decay can be effectively controlled with the Polar pickup system. The dual mode preamp allows the player to choose between two very distinct tone qualities. The first mode delivers the full frequency response of low impedance electronics, for a rich, full-blown "electric" sound. The second is balanced to produce the frequency response of the traditional viola, for a more "acoustic" sound. A 3-way toggle switch allows the player to select the desired pickup and electronics options. Additional controls include volume and individual bass EQ & treble EQ controls. Remarkably precise and stable tuning is accomplished entirely behind the bridge, in the manner similar to the fine tuners of an acoustic instrument. Standard viola strings are clamped securely as the string is tuned. No headstock scroll or tuners are required, so the balance point of the instrument is back toward the shoulder for optimum playing comfort.
