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."
Engineered stone and polished by fabricators, and assembled at the worksite. Engineered stone (US name) is also commonly referred to as agglomerate or agglomerated stone, the last term being that recognised by European Standards (EN 14618), although to add to the terminological confusion, this standard also includes materials manufactured with a cementitious binder. The quartz version (which end consumers are much more likely to directly deal with) is commonly known as 'quartz surface' or just 'quartz'. Breton S.P.A., a privately held company of Treviso, Italy, that developed large-scale Breton method in 1960s, is the dominant supplier of equipment for making engineered stone.
