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.

The subject invention provides a surface-placed a surface sound capturing microphone with a rotatable cable connecting member to allow the output cable extracted position to be simply changed. A surface-placed sound capturing microphone of the subject invention includes a connecting member 2 which connects one end of an output cable 3 for transferring an audio signal captured by a microphone capsule to a predetermined external instrument. The connecting member 2 is mounted in the microphone case 11 and is rotatable around a horizontal rotating shaft in parallel to the placed surface. The output cable of the microphone can be positioned at a horizontal extracted position where the cable is horizontally extracted in parallel to the placed surface and at a vertical extracted position where the cable is vertically extracted relating to the placed surface.
