Intermittent or failed contact causing guitar signal to cut out
What you need
*Before we start, it’s worth nothing that this process requires some soldering know-how. If you need a refresher, be sure to check out our A-Z guide here.
Guitar parts eventually wear out, especially mechanical parts that take a lot of use and abuse. Output sockets are a case in point and most of us will have experienced issues with our signal cutting out. Try wiggling two or more cables in the output socket.
If the signal cuts in and out with each cable, you can be pretty sure the output socket is at fault.
Switchcraft is a popular and reliable brand for jack sockets. You can get these from Allparts UKAssuming you’re not dealing with an original part on a vintage instrument, the sure-fire fix is to install a new output socket. In most cases, there will be just two connections. However, you may find a third wire if the bridge or trem spring claw is grounded at the jack socket, or if it’s a switching jack for active pickup systems.
A new jack socket waiting to be installedReplacing an output socket is pretty straightforward with Strats or Les Paul-type guitars because it’s easy to gain access to the socket. Semi-acoustics present problems because you will probably have to pull the socket, and all the controls, out through an f-hole. As for vintage-style Tele jack cups, you’d probably be best advised to leave those to a professional.
The wires are de-soldered from the jack’s solder lugs. This process will be reversed then the new socket is fittedAssuming that you can get at the socket, make a note of which connection is positive and which is negative. The negative (or ground) will usually be black. Heat a joint with a soldering iron and pull the wire away as soon as the solder melts. Then do the same with the other wire.
With the changeover complete, the jack cup is screwed back onto the Stratocaster bodyUnscrew the nut holding the socket in position and remove it, then fix the new socket to the plate or cup and solder the wires onto the new socket. Ensure the wires do not move as the molten solder is setting and never try to speed up the cooling process by blowing on a soldier joint.
