AcoustaGrip Concert Performer fits 4/4, 3/4 and most 1/2 size violins and violas.

2 layer construction. 1st layer consists of custom designed acoustical materials, delivering superior sound and comfort.  The other layer is unique as it attaches simply with air using micro-air technology.  Because it attaches with no glues or clamps, it helps preserve your violin or viola.  In addition, it sets the violin’s position at the most favoured angle for sound projection and ease of performance.

AcoustaGrip Adult Size Shoulder Rests share the following features:
The AcoustaGrip has no clamps that mute the violin’s sound.
The AcoustaGrip increases the volume of sound and adds better quality with more overtones.
The AcoustaGrip is very comfortable, ergonomically designed and stays attached with air.
The AcoustaGrip gives a secure hold for the violinist or violist and attaches repeatedly on & off.
The AcoustaGrip sticks without glue or clamps with no damage to the varnish, edges or back of your violin or viola.
The AcoustaGrip fits easily inside the instrument case, resting over the bridge to keep your instrument securely in place.
The AcoustaGrip protects your chin, neck and collarbone from sores and marks and alleviates the shoulder pain and restrictive movement of rigid, vice-gripping traditional shoulder rests.

AcoustaGrip, you can have the secure grip of a traditional shoulder rest without resigning yourself to the constant discomfort and restricted movement. Long practice sessions can be the joy that they were meant to be. You can focus all of your attention on honing your technique and playing more expressively without being distracted by the constant physical pain that all too often accompanies playing with a traditional shoulder rest. Clamping shoulder rests mute the sound of the instrument by restricting the natural vibrations of the wood. AcoustaGrip is built to allow these natural vibrations to flourish, utilizing a flexible acoustical material instead of rigid aluminum. While clamping shoulder rests are muting your sound, they can also cause visible damage to the edges of your violin or viola.
