Nope, i don't really use any oils, i've used a martin guitar polish a few times, but not to the extent that it would be to blame. My last guitar, a Taylor 414ce, started to get a lot of fret buzz because I left it out on a stand in my room, where the humidity and temp fluctuated, and that's why I've been extra careful with this one, always keeping it in the case, with a humidifier and hygrometer (don't know if that's what it's called) that tells me the exact humidity, temp, and keeps track of highs and lows. I'm 100% this is a Martin finishing defect so we'll see if they try to keep their reputation. I'll try to get in touch with them. Thank you guys for the concern though, I really appreciate your feedback!!! All of your ideas are very appreciated! Thanks again guys!

Whereabouts in the case do you store your humidifier and which type is it? It just seems strange for the problem to manifest itself during the short time you've owned the guitar and not during the previous five years.
