I have a 100 year old german bass that I never play. I want to move it downstairs to my basement office as a showpiece. However, my basement can be quite cold. I have a heater that I turn on when I'm down here, so the temperature fluctuation can be relatively large (between about 15-25 degrees Celcius?) Will the colder temperature damage my bass? What about the temperature fluctuation? Note: I live in Calgary Alberta, and it is very dry here.
