I put a dirty fingers in the bridge of my guitar a few days ago. It worked fine until I put the neck in. The bridge became really noisy. I resoldered everything and it's too quiet ,the volume keeps dropping, pinch harmonics are impossible, and the sustain is terrible. It also makes a terrible popping sound when I switch pickups. Anyone know wat the causes are?
bad soldering, messy wiring. if the metal of the wires touch solders or wires they arent supposed to touch, it could get messed up. maybe your cable or output jack on the guitar
