Hohner Jack socket

[chuggmiester]

The  Jack socket  on my bass is very hit n miss if I shove  the Jack plug in all the way nothing  comes out of the  amp if I pull it out 3to4mm it works  .the socket  has 3 wires 2linked to the active side of the circuit board  any ideas anyone

If it's a Fender style one like this then you can bend the contacts back:

However if it's a barrel jack then you will need to replace it:

Barrel jacks are notorious for going wrong, you’ll need to replace it and perhaps keep a spare handy if it’s your go to gig bass. 

You could try rolling up some sand paper and giving it a clean, but it’s a long shot.

If it is the generic non-enclosed bendy one (technical description!), don't push it back too far.

It's the barrel  type thanks for the  info

It's a barrel one but non standard. The threaded portion is wider than normal and actually screws into the wood with a slotted head. Mine has done exactly the same only working if you pull the jack out a little. These Jacks are not available from Hohner any more and they advised me to get one for another type of active bass (Hohner JJ or similar). This is however too narrow to screw into the wood and too short for the length of the hole. I am considering routing out the hole on the inside to 18mm to fit the nut into. Alternatively adapting the sleeve of a female socket.
