A musical instrument cable that is functional for use while walking around and playing an electric guitar or other electric instrument. This provides the user with a freely rotatable and noiseless solution to old style cables which twist up during use and eventually break down due to mechanical fatigue of the internal wiring. Using a typical audio connector plug 10 on one end and connecting to a length of coaxial cable 12 with enough length to strain relief a loop of cable through the guitar strap and butt end of the instrument, the cable is then connected to a rotatable electrical connector 16. The connector 16 internally uses mercury to make the electrical connection between the moving contacts within the connector 16. The other end of the connector 16 then attaches to another length of cable 12 and to another connector plug 10 on the end of the cable 12.
