6 grand isn't bad for an acoustic that I know is carefully made (not slapped together and painted nice.. Gibson), will sound like a billion bucks, will last forever even in this weather in Alberta
Michigan's weather is probably a lot like Alberta; long, cold, dry winters that ruin guitars! Even with a whole-house humidifcation system on my furnace, it's forced air heating and it still gets down to 25% humidity or so. To put in perspective, the Sahara Desert's RH is usually around 25%!!
And wood being wood, and nitro being nitro, I go the extra mile. Here's what I do to preserve the playability and everything else for my acoustic and electric guitars:
I never had good luck with in-case humidifiers. The guitars were always too wet where the humidifier was, and too dry everywhere else. Over the years going back to the late 60s, I started with a half of a potato in a soap case with holes in it (the standard thing back then, smelly and ineffective), then when they started coming out with little round plastic cases with plaster of paris that you'd soak in water and stick in the case, I switched to that; then soundhole humidifiers, green rubber noodle doodads you'd clip to the strings,and on and on, I tried everything. Basically all of that was a complete waste of effort.
In 2000 a friend on the old PRS Forum, Scott Peterson, said, "They have room humidifiers now that filter out the white dust, I just keep the guitar and case in the humidified room, the guitar doesn't know what time of the year it is and it works." So I started doing that, and got my best guitar care results.
It's a pain in the rear, you have to refill the water every day or two, but I'm able to keep the room where I keep the guitars at a constant 40% in the winter months. As a result, the guitars can go a long time without needing adjustments, without finishes getting screwed up, and so on. The acoustics stay playable.
For the last couple of years, I've used an Air-O-Swiss that puts out a warm mist. But I've also used one of the steam-based ones with good results. Very inexpensive guitar insurance. You can find good ones for under $100-200.
Note: you don't need one of those big floor models, they're awful., and difficult to fill and control. Tried that, too, at one point.
