I have a BC Rich Warlock bass (bronze series).. I was playing and went to turn the volume nob when, my bass just quit. I took the back plate off and noticed a wire had broken of its soder. The wire is black and comes out of the body with a white wire, (they are stuck together side by side. The wire is only long enough to reach the volume and tone nob, (barely reaches the tone nob). I think these wires come from the pick-up. Does anyone know where this wire is supposed to be attached to?
