A pickup cable for a stringed instrument can switch between the output of the direct vibrational sound of strings and the output of the sound from the stringed instrument body generated by the vibrations of the strings and can also simultaneously output both the sound components. The pickup cable for a stringed instrument includes an input terminal to be inserted in a jack of the stringed instrument; a microphone to collect and convert sound of an internal space of the stringed instrument into collected-sound electrical signals; and an output terminal to output the collected-sound electrical signals. The microphone is incorporated in the input terminal.
