if dont wanna bring the geetar out to anywhere,
1) Find electro contact cleaner, non oil based
2) Open up wherever the pot is situated
3) Spray contact cleaner into the pot with scratchy static sound(not too much though)
4) turn the pot few times
5) Plug in cable and to the amp, rock out time, while checking the vol pot and see if it still giving problem
and if theres still static sound, heh, dont bother spraying anymore,
1) Find anyone who can travel to your place and help you check out the pot
2) Buy new pot
3) ask that someone to help change the pot
4) Plug in cable and to amp, rock out time again, while checking the new pot
and if cant find anyone, then i guess will have to bring the geetar outside of house, visit either
1) Sweelee, if theres electronic warranty of somesort for geetar bought from them and let them know of the problem
or
2) Bring to any reputable geetar tech and have them check on the pot
