There are plenty of subjects related to storing a guitar in various conditions, but most talk about exposure to direct sunlight or other notable sources of heat or are a bit vague.
My problem is that I live underneath the roof and during the summer heat waves it can get a little unbearable. I'm not 100% sure what the exact temperatures inside are (it can easily be over 30 degrees Celsius outside), but it's really uncomfortable.
Now, I don't plan to ever leave my electric guitar next to a heater (winter) or in direct sunlight. I am however worried about the effects of the general temperatures on my guitar if I just leave it in my room. There would be no sudden temperature changes (unless I actually decide to carry it downstairs - I can FEEL the temperature drop / rise going from floor to floor), it would just generally be warm during such days.
What are acceptable temperatures for an electric guitar? Should I be worried about mine? If these conditions aren't good is there anything I could do to make sure the guitar doesn't get damaged?
I could, of course, ask someone to store it for me during such days, but then I can't play. :(
