Abstract
In an electronic musical instrument, an expression control circuit constituted by a first variable resistor is connected in the path of the tone signal. A second variable resistor is connected in series with or in parallel to the first. A third variable resistor is connected in shunt between the output side of the expression control circuit and the ground. The second and the third variable resistors can adjust the variation range of the tone signal at the output of the first variable resistance.
