PROBLEM TO BE SOLVED: To conveniently control and to easily and speedingly change the tone by generating monophonic or stereophonic sounds by mixed or separated electric signal outputs by a musician. SOLUTION: A switching element 114 connects a pole 108 and a terminal 110. Volume control circuits 116 and 122 are connected to the same output channel of an output connector 104 and provide monophonic output of a pickup and a converter. The characteristics of the monophonic output are determined by the mixture of the pickup signals and the converter signals which are controlled through voltage dividers 118 and 124. On another switching condition, the element 114 connects the pole 108 and a terminal 112 and the circuit 116 is connected to another output channel of the connector 104. The circuit 122 is connected to the output channel of the connector 104 and provides the stereophonic output of the pickup and the converter. Two channels of the stereophonic output are controlled through the dividers 118 and 124. |
