Repair Input Jack on Guitar

Here we see one of the leads has become disconnected from the input jack terminal. As you can see, the terminal has solder. This needs to removed and replaced with fresh solder as to avoid a cold solder joint.

Step 1: Applying Fresh Solder

Using my helping hands, I position the end of the lead so I may apply solder to the tip. The old solder on the terminal has been removed and new solder will be added there as well.

At this point we also want to slide a piece of heat shrink tubing onto the lead so we can insulate the finished joint.

Step 2: Successful Solder Joint

As you can see the joint is nice and shiny, signifying that the joint is solid and is allowing a strong connection. This is important for the tone of the instrument.

Step 3: Insulating Using Heat Shrink Tubing

Here I used a piece of 11/64" heat shrink tubing. Now that the joint is secured I slide the tubing back down the lead and over the joint.

Using the soldering iron I carefully apply heat to shrink the tubing tight around the joint. Be careful not to burn the tubing!

Step 4: Finished!

You can see the tubing is tightly wrapped around the joint to provide good insulation. All there is to do now is screw everything back in, plug in and jam!

    I would recommend getting rid of the female quick connect fitting and soldering that wire to the jack as well.

    yeah, it would have saved some trouble in the future for sure. Thats probably why the first one came off.

    The ground wire has also come loose and the bass buzzes like all hell. so if I ended up fixing that Ill be sure to solder that 2nd lead as well.

    thanks for checking out my instructable!

    I suppose it is since the signal is being outputted to the amp. I suppose I called it input jack because you plug the cable into it.
