ABSTRACT:
A manual control lever for plucked instruments supplied with electric sound amplification has a rest plate for the player's plucking hand. This rest plate is located above the strings and held by a lever arm which has rotary bearings, allowing a motion parallel to the top and further an up-and-down motion vertical to the top of the instrument. The parallel-to-the-top-motion provides the necessary movability when plucking the different strings of the instrument. The vertical-to-the-top-motion provides a continuous control of sound elements, preferably volume and timbre, through the fact that the mechanical means drive electronic members converting the mechanical movement or pressure into a continuous variation of voltage or current. The volume is controllable in two ranges: Firstly from zero to the normal level, and secondly from normal level to a maximum peak.
