check your guitar cables, do you use the same one for all your guitars?? i dont think you will need a new 1/4" jack socket, its unlikey to have been broken or damaged, it is more likely that the one of the wires has come off, take off the socket, you do this by loosening the nut around it, then the socket should come out, there should be 2 wires attached to the 2 terminals on the socket, if one has come off then simply solder it back on, if the problem isnt there then look at the wiring around the pickups/pickup selector/ and vol and tone pots, check that the wiring hasnt come off there, do these checks and then come back to us, and also give us some more details on the bass, manufacturer / model??
Good luck.
