I thought about starting a new thread, but decided to just post on the end of this one.
As a further exploration of the claims of the stability of Carbon Fiber to extreme temperature changes, I just conducted another experiment. I left my guitar out in my vehicle overnight, with the temperature dropping down to 19 degrees Fahrenheit.
After bringing it inside to a 74 degree Fahrenheit house I immediately opened the case. (I would never do this to a wooden guitar...Yikes!!!).
Other than the strings needing tuning, no observations of ANY problems!!!
My Peterson strobo-tuner that I accidentally left in the case, would not read until it warmed up though...oops...
Now to go warm up my fingers...Eeekkk...
