My Guitar's input jack is as loose as that sailor-mouthed, tattooed, forty-year old floozy hanging out at the truck stop. Problem is, when I start moving around a lot the goddam cable falls out of the jack and sound is lost. Awful. Nobody likes that. How do I fix it so the cable stays in. I googled loose input jack and I did not find the right result. It's on the base of the body; not recessed.
