A timbre selector includes a first signal processing unit, a second signal processing unit and a first switch. The first signal processing unit includes a first input terminal, a first filter and a first output terminal. The first input terminal receives a first tone signal. The first filter processes the first tone signal to generate a first processed signal. The second signal processing unit includes a second input terminal, a second filter and a second output terminal. The second input terminal receives a second tone signal. The second filter processes the second tone signal to generate a second processed signal. The first switch is connected to the first output terminal at the first position. The first switch is connected to the first and second output terminals at the second position. The first switch is connected to the second output terminal at the third position. |
