Manufacturers
There are several present-day producers of the contrabass clarinet. Selmer Paris makes a rosewood version (model 28) looking much like a longer version of the bass clarinet, with full keywork, and Leblanc USA has a plastic instrument in a similar long-body design. Leblanc Paris builds two versions made of metal, model 340 (known as a paperclip contrabass due to its folded shape) with range to low C, and the model 342 (similar in shape to the Selmer and Leblanc USA models, with range to low E♭). In 2006 Benedikt Eppelsheim introduced a metal contrabass clarinet with a folded shape somewhat resembling that of a baritone saxophone, described as a full Boehm system instrument with a full set of four right hand trill keys.
