Due to circumstances beyond my control, one of my guitars (thankfully, my cheapest one) got left in a car trunk overnight and the temp got down to the mid 20s. Im hoping it wont be damaged. Im trying to do the proper thing and slowly warm it up and all. What do I look for? I imagine they are probably more resilient than I think cuz Im sure over years, guitars were subject to all kinds of conditions as bands were trying to make it and touring in vans in all climates et cetra. But I try not to push my luck..
