An output jack for an electric acoustic guitar is installed at a guitar body and is adapted to receive a first plug connected to one end of a first cable which couples an output tone signal of the guitar to an external power amplifier. The jack further comprises a receptacle portion inside the guitar body for receiving a second plug connected to one end of a second cable, the other end of which is coupled to a pickup device. The output tone signal of the guitar is transmitted to the external power amplifier via the second cable, the second plug, the jack, the first plug, and the first cable in this order. The jack further comprises an electromagnetic shielding member for shielding the second plug from an electromagnetic induction against the second plug.
