The W-C2 is a 62 key duet with the 'Chromatiphone' keyboard, invented in the 1920s by Hugo Stark. This system is closely related to the accordion 'C-system'. The Chromatiphone Duet models feature customized reed scaling.
The standard W-C2 model has French polished walnut, Padouk, Maple, or Ebonized flat ends. Raised ends and other types of wood are optional.
