Re: Mail-Ordering Guitars During Arizona Summers
I'll just say the same thing I replied in email.
Heat is not a problem, until you get to the point things catch on fire of course, but heat is fine on a guitar. Cold is always an issue, cold means contraction, everything shrinks, everything become more fragile. Yet, I ship all winter long without incident. What should never be shipped in the winter [or only shipped express] are guitars like JEM10's and PS10's, guitars that have purfling across the full body. Purfling doesn't shrink, the wood does, pinching the purfling ends together forcing them upward thru the clear as that's the only place they can go, so you will get bumps in the clear at every joint best case, worst case it blows the clear off over the joint.
But heat does the opposite. If you're worried about checking like you'd get i n an old lacquer finish those happen over months of expansion and contraction, like guitars left in an attic constantly expanding and contracting with the temperature.
