Scratchy Volume Pots, Tone Pots, and Switches Here is a thread to let people know ways to fix or improve the sound if your squier if it has a scratchy Volume pot, Tone pot, or switch. a little trick for those cracks and pops in the volume and tone pots, and also the switch. If you plug the guitar in to an amp, just take about 10 minutes, and turn the crackeling knob a whole bunch back and forth, it works well with the entire side of you hand you can just roll the knobs then. For the switch just switch it back and forth a ton. What you are doing is rubbing the dust out of the pot. after a little you should be able to hear some if not all of the cracks and pops going away. most guitars just need to get the dust out of them and some corriosion off the pot. some pts, however are helpless causes, and just need to be replaced if that trick does not work.
