Shubb Shubb Shubb is a company that specialises in producing capos for all kinds of stringed instruments. The company was formed in 1974 by banjoists Rick Shubb and Dave Coontz. Shubb capos remain a top-selling capo forty years after their invention. Shubb wanted to create a capo that would not make his instrument go out of tune, which has resulted in ongoing efforts to refine his invention. The Shubb Capo utilises an "over-centre" locking action, which is lever operated. The design includes a screw for adjusting the clamp's tightness, and has been described as "a turning point in modern capo design."
