The accordion has zinc reedplates and the bass sound is in line with it – this kind of bass sound has to be search from today’s instruments. The diskant side has one register switch that connects to the round “revolver” behind the back plate. The register always moves the revolver with one stop and at the same time the register lists moves. A small screen is also connected to the system on top of the diskant body. It shows whether the accordion has two or three voices enabled.
