Like it or not, winter is here. Cold weather means snowmen, scraping the car windows, snow ball fights, and making sure the guitar is humidified. Cold weather means dry conditions which translates to the possibility of drying the wood of your guitar, and getting it out of whack.
Every fall, and winter I use my guitar humidifier. A new one each year is wise. My choice is a dampit. Every Sunday I remove the humidifier from my guitar, dip it into a 16-oz water bottle filled with distilled water. I squeeze the excess water, wipe it dry, and let it set until the end of our gathering. When we are tearing down the gear, I slip the dampit in the sound hole and pack the guitar back in the case. I have owned high-end guitars for several years (from Martin to Taylor) and have never had an issue. You paid some serious coin for your axe and it is one of your most important tools, take care of it!
