KUN Solo Violin Shoulder RestTwo years of R&D went into the creation of the Kun Solo. The slightly broader cushion on the shoulder end provides more comfort. The patterned cut out in the Solo's sponge rubber reduces weight, improves grip, and ensures air flow around the shoulder and neck. A simple, quick adjust lever, eliminates the need for screws and offers an infinite number of positions. Clever collapsing mechanism makes for easy storage.
