The Protg violin/viola shoulder rests offer three unique layers of acoustical material, each of a different density and responsiveness. One layer is made from a special acoustical material, delivering superior sound and utmost comfort and a secure hold while protecting against bruising, sores and marks on chin, neck and collarbone and relieving shoulder pain. One layer attaches simply with air to the back of your instrument using micro-air technology. The colored layer gives this Protg model added projection, increased resonance and allows the musician to create the maximum overtones for the violin or viola. The ergonomic design of the Protg sets the violin or viola's position at the most favored angle for ease of performance and the best sound projection. Protg uses no clamps or glues to stop the woods vibrations or damage the violins finish.
