Pirastro Korfker Viola Shoulder Rest- Model 2
The Korfker shoulder rest is made by Pirastro in Germany. It is the first shoulder rest made of flexible maple, which means it is custom mould-able for the ultimate comfort fit. The heat mouldable frame is superlight, while producing a wide dynamic range. The minimal use of rubber improves sound characteristics and allows a wider diversity in note articulation. The feet mechanism allows precise adjustment for height, tilt and alignment.
