Tip: You may need to use a pair of pliers (a Leatherman is the best) to gently hold the potentiometers/output jack in place from the back whilst turning your wrench on the outside of the guitar. Use a Wrench to tighten loose hardware on the output jack and potentiometers before screwing the back plate back on.Then turn the knob back and forth until the scratchiness has disappeared.
