Under good maintenance, an electric guitar can last for many years. However, these guitars are fitted with many electrical components and circuits which with time may wear out. Also, some of the parts of your guitar may break down thus necessitate repair or replacement. Some of these repairs or replacement may be easy to perform while others could be difficult and necessitate replacement of the entire instrument.
In case your volume and tone knobs starts to produce snapping or popping noises via your speaker whenever the instrument is plugged in, or if the signal is faint, incoherent or disappears altogether at some sections of the controls, then most likely the controls are clogged with dust or dirt. Turning the knobs vigorously back and forth may help restore the controls normal functioning.
Crackling sound could also be as a result of loose jacks due to repeated plugging and unplugging action when using the instrument. Normally, the crackling sound is caused by a disconnected ground wire, a problem that can be fixed by locating the wire and soldering it back.
The sound your electric guitar produces depends entirely on the functionality of its pickups. Therefore, if one or all of the instrument’s pickups have turned out to be defective, then replacing them with some suitable ones is necessary. Avoid rewiring your electric guitar; for instance, by replacing your five-way with an on-off switch or fitting a coil-tap or phase switch over any two close pickups that are working. Doing this may cost you the entire instrument.
As aforementioned, replacement of your entire guitar may be necessary especially if the damage is intense like your instrument having a broken neck. If that is the case, then consider this most exclusive collection ever seen. You’ll definitely get your pick.
