Note that "jack socket" is redundant because a jack is a socket.

(And, likewise, what goes in is called a plug, not a "jack" or "jack plug".)

Having now got inside one I see why they last no time at all with loads
of jack insertions/extractions a gig, swapping guitars. No name socket
in otherwise good name guitar.

That kind of barrel jack is used in acoustic guitars, where it has to
go through a thick block of wood, like an end-block.

If there is any possibility that it fits you instrument, you should use an
"open frame" jack made by Switchcraft:

These things are tough and last for years.

The tip contact can be bent slightly to adjust the tension needed to remove the
jack.

Once in a while, polish the contacts with metal polish like Brasso
or Silvo, and you're good.
