Never heard of a jack wearing out & have never experienced any jack problem. Possibly the cable jack could be a suspicious culprit. Guess that is why it maybe in best interest to upgrade a lower quality female jack to a quality Switchcraft, made in the USA, product. My '61 P bass ( tort & flats) has been played hard through out the years and I have had no problems with the jack. Go figure. . .
I'm speaking of BARREL JACKS, which do wear out sooner than a Switchcraft #11.
