AcoustaGrip Concert Performer Shoulder Rest 

No more sores, marks or shoulder pain! 

The two-layer design of the AcoustaGrip Concert Performer is vital to its effectiveness. One layer is custom-designed and produced acoustical material, delivering superior sound and extreme comfort. The other layer attaches the instrument simply with air to the back of the instrument using Acoustagrip's proprietary micro-air technology. Because it attaches with no glues or clamps, AcoustaGrip helps to preserve and protect the quality and condition of the violin or viola. In addition, it sets the violin's position at the most favoured angle for sound projection and ease of performance.

• Increases volume, adds quality with more overtones
• Comfortable, ergonomically designed, and will not fall off.
• It gives a secure hold, attaches repeatedly
