Hi There, I've got an old stratocaster and the input jack has become problematic. If the guitar cable moves slightly it sort of seems to lose ground and you get some serious humming and noise etc and have to wiggle it. I've checked the connection, made sure it's tight and theres good contact with the lead.
I've read somewhere that sometimes as jacks get older the plates can suffer from oxidation or something and need to be cleaned with a wire brush and or wd 40 (contact cleaner). I was just wondering if any of you have experienced similar problems to this and if I need to replace it or can it be saved.
Thanks for any advice,
Kris.
