ABSTRACT:
A device for continuous pitch variation has rotary support levers which connect the extension piece of the neck flexibly with the body of the instrument. A rotary string holder is mounted on the extension piece of the neck and a ribbon connects the string holder with one of the rotary support levers (via a roller). A tension spring connects one of the rotary support levers with the extension piece of the neck or as a second possibility with the body of the instrument. A counterweight is mounted on another rotary support lever which is so connected with the extension piece of the neck or one of its support levers that, when sliding the neck, an opposite movement of the counterweight will be effected. A locking or stop device gives the player the possibility to lock or to open the mobility of the neck.
