Finally! An endpin stop that works! For both cello & bass. Designed by a professional cellist, SmartStop sticks securely on most surfaces including marble, wood, laminate, linoleum, and more. With a slim, light profile, SmartStop will fit easily into the pocket of your case. For cellists, our "cello" model works for all endpins (with rubber tips or sharpened tips) and "hybrid" model works for cello or bass. Both feature an innovative design with multiple holes added to the center of the stop which allows cellists & bassists with sharpened endpins to make micro-adjustments to their position within the stop rather than moving the whole stop. Made in the U.S.A.
