Guitar, ukulele has a lot of fragile parts, and the jack is one we often overlook. In fact, if a string is interrupted or the gear is stuck in a certain file, it can be done, but if there is a problem with the jack, it will be finished. Even more frightening is the sudden misfiring in the show - no matter how cool your guitar looks, no sound can be too embarrassing.
The good news is that broken jacks can often be fixed. And with just a few simple tools, you can do the repair yourself.
Treating guitars, ukulele's damage is like treating any problem, and governance is worse than prevention. So please check your jacks frequently. If it is loose, use a pliers to tighten the screws as soon as possible.
Minimizing the tension of the cable to the jack extends the life of the jack. Wrap the cable between the strap and the body so that even if you accidentally step on the line, it will not be hard out of the jack, causing damage.
When there is a problem with the sound signal, many people's first reaction is that the jack is out of order. But please don't just come to this conclusion, the biggest possibility is that your cable has a problem. Try changing a line first. You don't want to remove the car engine before you find that you have no oil.
If your cable is fine, but the guitar still has no sound, then you should rule out the second possibility: your pickup gear is faulty. Quickly move the gear up and down to see if the guitar will sound. If there is sound, your pickup gear needs to be cleaned or replaced; if it still doesn't move, let's check the guitar jack...
The first possibility is that the wires in the jack are broken. If the jack is loosened inside the guitar, it is possible to break the wire. In this case, you need to weld it.
If you don't see a broken wire, check to see if your jack securely fastens your cable. The long metal piece in the picture plays this role. Insert the cable. If the plug sways or falls out, we need to adjust the metal piece.
Gently push the metal piece toward the center of the jack, making it slightly tilted, but be careful not to break it. A little bit, then try to insert the cable. If the plug of the cable is well fixed and no longer shakes, then try to play the bullet with the speaker. In theory, your jack has been fixed. But don't worry about putting it back...
After handling the jack, clean the top of the long metal piece. Metals are easy to attract dust and rust to damage the guitar. Use sandpaper, sand or a screwdriver to scrape the scrape and contact the tip of the cable.
Check each time you put the guitar parts back. Do not press the wires under the jack plate, missing a screw or scraping off the paint.
