faulty tone knob

Discussion in 'Hardware, Setup & Repair [BG]' started by Chris J, Feb 28, 2002.

  1. My girlfriend is buying a guitar that's a Strat copy. It's a Lyon made by Washburn. Anyway, I heard that this one guy had funny tone knobs that would start to hum and cause static if he didn't use them for a while. Then when he turned them a little the hum went away. If this happens to this guitar what could be the problem? Dirty pot? Need a new pot? Just FWIW it's got the s/s/s pup config, passive, one vol. 2 tone and a 5 way switch. Thanks everyone.
  2. C'mon guys don't stiff me like this.
  3. Sorry first time i logged on today ;)

    Erm well if it happens, i would just open up the cavity, clean it out. Dust is very annoying and loves living in guitars. Try spraying some CRC (the blue can only, you can CRC in other coloured cans, but they serve different purposes), or WD40 (doesn't last as long though).

    It could be a shielding problem, ensure that the leads soldered onto the pots are all ok, if they look dull, whip out the soldering iron and resolder them, keeps it fresh.

    If it still does it, try replacing the pot or depends on how much a electronics head you are, i would maybe place a capacitor (non polarised) of a high value, say 10 pF, across the two outer legs of the pot and see what happens, i would just experiment with different values, and see if it filters out the hum.

    But eh thats just me.
