My C1's tuners are original, so they're ~8+ years old. It has brand new strings on it, and I always use a bit of #2 pencil on the nut and in the actual string hole on the peg when I do changes.
That said, the tuners are creaking (all of them, all of a sudden ) after my last string change, and I'm not sure why. When I tune either way, they'll make a ping sound, and the string will "skip", so to speak so that I can't get it in tune correctly. It'll jump just a little flat/sharp regardless of how much I twist.
Is this something that I can fix with some oil/graphite, or should I just slap new tuners on it? This was one of my kick around guitars, so it spent about a year at my Drummer's place in a pretty dusty basement.
