The practical, uncomplicated design of the Kun Original shoulder rest, with its simple adjusting mechanisms has made it the favourite of amateur and professional players alike.
A note on the Kun Original: the T-shaped feet on this model should not be removed to make the rest fit into your instrument case. Regularly pulling the foot and round drum out of the L-shaped end member and then reinserting it weakens the composite plastic from which the shoulder rest is made and can damage the shoulder rest. If you need a more compact rest, try the Kun Collapsible or Solo model which fold for easy storage.
Also, the Original also can not be modified with Collapsible end members.
The Kun Original Shoulder Rest is available for viola, violin 4/4, violin 1/2 & 3/4 and mini (1/8 & 1/4).
