Abstract: The extendible musical instrument cable has a housing having a pair of sidewalls and a peripheral wall defining, preferably, a flat cylindrical housing. An opening is defined in the peripheral wall. A mounting loop is disposed on the housing. A cable reel is rotatably mounted between the sidewalls of the housing, the cable reel being spring-biased in a first rotational direction. A ratchet assembly controls the rotation of the cable reel against the spring bias. A fixed electrical cable, terminated with a male phone plug for connection to a musical instrument or to a piece of electronic equipment, extends from the housing. The fixed electrical cable is electrically connected to an extendible electrical cable that is coiled about the reel. A free end of the extendible electrical cable extends through the opening in the peripheral wall of the housing, and is terminated by a male phone plug.
