STRINGS: NS Electric Strings by D'Addario™ are standard.  Compatible with solid and stranded core viola strings.  Synthetic core strings are not recommended.

PRECISION TUNING HARDWARE: 40:1 fine tuners are mounted on the body behind the bridge for precise, stable tuning. Automatic string clamping allows for quick, easy string changes.

BRIDGE PICKUP: The Polar directional piezo pickup system responds selectively to either vertical vibration  (for remarkably even and sustained plucked/pizzicato sound, like a mandolin), or lateral vibration (for dynamic bowing, and a percussive plucked sound).

ACTIVE ELECTRONICS: Dual mode preamp allows the player to choose between two distinct tone qualities: (1) the extended frequency response of modern low impedance electronics, for full-blown "electric" sound, and (2) active electronic shaping to replicate the frequency response of the traditional viola, for a more "acoustic" sound. A three-way toggle switch allows the player to select the desired pickup and electronics options.


  • Volume
  • Treble EQ
  • Bass EQ
  • 3-way Switch for Polar pickup:
    • forward - vertical string vibration (for sustained pizzicato)
    • center - lateral string vibration, full frequency for arco
    • back - lateral string vibration, "acoustic" timbre for arco

HEADPHONE JACK: 1/8" headphone jack for silent practice and self-monitoring.


SHOULDER AND CHIN REST OPTIONS: The Custom Shoulder Rest is a standard with the CR Viola and can be formed by the player to fit the body perfectly.  As an option, the violin can also attach to NS Design's revolutionary Balanced Shoulder Rest, which “floats” the instrument in the desired playing position without being “clamped” between the jaw and the shoulder.

The contoured ebony chin rest supplied with the instrument is designed to work comfortably in tandem with the Custom Shoulder Rest. The optional Adjustable Chin Rest is also available for players wanting a more extensive range of position adjustments for more customized fit and comfort.


NS VIOLA CASE: Customized for the NS Violin, this standard hardshell case with handle and shoulder strap includes separate compartments for shoulder rest and accessories, a bow compartment and exterior zipper pouch.  Made with durable Cordura® fabric, 3.2 kg (7 lb) loaded weight.

FLIGHT CASE(Optional):  Plywood, aluminum sided. 6.3 kg (14 lb) loaded weight. Padded, form fitting interior. Holds bows, shoulder rest, output cable, and extra gear, with lock and key.
