So, I've had the TaylorSense installed in my K65ce for six months now.
Stuff I've noticed (perhaps obvious to those that track guitar humidity):
1. I always thought that here in Northern California, we had a nice blend of temperature and moisture and I never did anything special with my guitars. On stands all the time. Rarely in the cases. How wrong I was.
2. With TaylorSense, I could see that my guitars were going very low . . . 32% sometimes. Just putting in the case raised the humidity an average of 5% without doing anything else.
3. With some DampIts (3 in my case) - see Jim Taylor dry guitar videos on YouTube - the guitar, over a couple of days, climbed into the 50's. Take it out of the case for a day, low 40's. A DampIt by the headstock by itself didn't do much. These are DampIts (wrung out) in the soundhole. I also added their soundhole cover which works well on Taylors.
4. So nice to check the guitar in the case at anytime within bluetooth range. The guitar can be checked in the case, on the stand, while playing etc.
Obviously, any of this can be done without the TaylorSense. But it sure makes it easy. And, I've learned more than the price of admission
