Hello. I am new here. I posted this on Telecaster board. Probably should have put it here as it is more of a general guitar topic. Thanks.


I have a 75 Telecaster that I recently acquired..All the electronics are original.There was a little popping at the input jack if you wiggled the cable some , so I checked the solder connections and all seemed fine..Took it to church yesterday and it was really bad. It is an old building with old wiring and maybe not even grounded , but my bass works fine there with no popping issues..So I get home, inspect the jack plug again, looks fine, but re-soldered connections anyway, still pops. So I went ahead and soldered in a replacement jack and it works fine. I am curious how the old jack can be in such perfect looking condition and still act up ? Is this a normal happening for older instruments ? I hated to replace the jack on a vintage guitar, but it is in a hole and cannot be seen anyway. Any input is appreciated.

A thin film of crud and corrosion inside old sockets is common. It doesn't have to be bad enough to be visible.
Go to a gun store and buy a breech cleaning brush and some cleaning oil.

Just make sure you don't use too much oil, and get it all out and off before you plug in again.

It is a output jack that is the problem . :lol:

I don't know what you mean about "popping " !

1 - Cable come out ?
You just have to bend the positive contact to have more tensionand guitar cable will not pop out .

2- Noise , pop ?

A jack is made by few parts press together , they might be loose after many many years . Only way to fix is a new jack . Buy a good Switchraft jack , no import jack please.

3- Corosion ? put new jack . Most of the time corosion may come back if you don't use the jack often. The thin protect layer on the steel is removed by lots of use an do not protect the steel from corosion.

Keep old jack in safety

Thanks.. The popping is like a crackling noise , but very loud, like it is losing ground....

I'd replace it with a new one and throw the old one in the case....an input jack is not a high dollar item.

Put new jack if bending the positive (+ ) do not fix the problem

No, but the vintage Tele jacks also aren't easily installable without special tools.
If you buy a third party jack cup and simply screw it in, you reduce the value of a vintage guitar.

It's possible that the jack's sleeve has become worn with age and use, and now fits a plug less snug than it originally did. If so, the ground contact is no longer being consistently maintained which usually results in spurious-and-periodic noise. In this instance, the jack must be replaced. Save the original for "posterity".

Arjay is quite right on that score. I've had it happen to me in the past. Bending the positive terminal so it puts more pressure on the tip will help keep the cable plugged in and it will also put some side load on the sleeve improving the ground connection. Cleaning the sleeve and tip occasionally are also good ideas but if the fibre washers are faulty or if the metal is cracked anywhere you'll get popping and the cheapest solution there is to simply replace the jack. +1 for a good Switchcraft jack. Good luck with your repair and let us know how it went.

Another possibility here is a bad cable or out of tolerance phone plug. Jacks not only wear but so do phone plugs. Some Asian made plugs are ever so slightly smaller than the USA standard diameter to begin with which could also cause the exact same symptoms. So would a problematic cable.

Everyone is so quick to replace the jack. Yeah that might fix it but then again it might not. Try a USA made cable with Switchcraft, Neutrik or G&H plugs on it.

And the other poster was right, changing jacks on a Telecaster is a bear without the very special tool from Stew Mac just for that.

Must be talking about the Jack Cup retainer, true it does help having the retainer clip tool. I found one for $14.
