Fender Squier 15 input jack

[JulianW]

Hi there,
I'm trying to replace the input jack on a noisy old Squier 15 I've been given. Trouble is the old one (branded LS) had two connections and was earthed to the faceplate and the one I've got to replace it has four connections and no earth. Oh yeah, and the old jack had already been disconnected, leaving one white and one black lead. Can anyone help me (a rank amateur!) sort this out please? The genuine Fender replacement is different from the old LS one as well. Check out these pix to see what I mean. How can I get this thing working again?
All help gratefully received.

Your four leg jack would work, but really it is not the sort to try to cram into the spot of the old one.

Does not the new jack need a larger hole to start with?

Why not just get something like a plain old Switchcraft #12A?

Go here: Antique Electronic Supply
Find stock number: W-SC-12A

It will look like this


And there will even be this little wiring digram



YOu have two wires, black and white. I don't know which is which, but one will be ground and the other will be the input signal from the jack to the amp circuit.

Look at the wiring diagram. Solder a short wire from SWITCH to SHIELD on the jack, and connect the grounded wire there. SOlder your signal wire to the SIGNAL pin.

Hi Enzo. Thanks for that, I guess I'll just have to get a voltmeter on the wires and sort out which is which. Looks as though the Switchcraft is the way to go ... the wiring diagram is handy and I did have one of those jacks around somewhere. You're right, the four leg one does need a larger hole.

Hello again.
Once again, thanks for all your help Enzo. The jack I had in my toolbox was a piece of cr*p which fell apart when I tightened it up. I got a Switchcraft jack and it is a great little jack, far superior construction and easy to solder. The amp's now up and running again for the first time in years!
By the way, looks as though the white is the signal wire and black the earth.
