OK, this is 'out there' I'm afraid, but maybe I won't be out there alone. I don't know that Dave Bowers and I are the only guitar pickers in the bunch, but when I go major or full time, I will have a classical guitar with me for performance, and probably an archtop. For those who may not know, changes in temp are not good for the tops of good guitars; said tops are thin and built to resonate, but they don't take kindly to a coach sitting in cold/heat/change. In a house, most luthiers insist on us keeping the guitars at 40% + humidity. I've done this for a while and I have some common sense (take it with you, keep coach plugged in w/ thermostat set, etc), but I wonder if anyone has counsel? Thanks again.
