I'm fascinated by the concept of buckle rash on the backs of guitars, for some reason. I've seen countless listings on Ebay and Reverb over the years that mention none, or slight, or a lot, or whatever. It seems to be universally acknowledged as a bad thing, at least from a sellers perspective. So why do some guitars have it? Do you wear a belt when you play? (I never do). Do you avoid causing it at all costs? BTW, buckle rash wouldn't prevent me from buying a guitar, but I prefer my guitars not to have it, I guess. But maybe I've been conditioned by years of seeing "no buckle rash" listings!
