So I have a P Bass with a top mounted jack that is unreliable. The signal cuts out if you wobble the cord around. This isn't the first instrument I've had to replace a top-mounted Switchcraft style jack because of mechanical damage. Is there an alternative piece of hardware that would be more durable? Will it fit within the tight routing channel of a P bass? Maybe a locking jack? I am willing to alter the 13-hole pickguard to fit a more robust jack, but not willing to route the body wood. Was looking at the Strat syle jack plates, but it doesn't look like it would fit. As a last resort I could buy new cords with right-angle jacks so less flexing and stress occurs, but that would be more expensive and more hassle than replacing a small part. Suggestions?
