Upload an image so it will be better to identify them a better way to know is to connect the device and go testing cable x cable. Usually they are three cables one of earth and two of audio the one of earth is identified x being thicker q the other two. Start connecting the ground ... I say if it is a bass guitar. Since you do not specify aq under t refer.
