Hi there, I would be grateful if someone who owns a Musicman Sterling SUB5 could send me a picture of the wiring inside. The two wires (black and red) got disconnected and I didn't really know how to connect them. So I brought it to a guitar shop so that they repair it. After repairing, I noticed that when I turn the bass knob to full, there is actually no sound. The treble knob is doing good. Thanking you for your help! Cheers
