Re: Buckle Rash Prevention?........
Actually, a lot of "buckle rash" is often "button" rash. A simple button can cause damage, especially to a guitar made of soft wood like mahogany (Les Pauls, SGs, etc.)
A Tee or Polo is mcuh safer around your guitar than your Western shirt with the metal and pearl buttons.
I once answered an ad for a Les Paul Custom. Beautiful guitar, about two years old.
Unfortunately, the owner was a jazzer who gigged with the guitar five nights a week while wearing a tuxedo! The shirt studs wore a hole in the back of the guitar about 2" x 3" and about 1/2" deep!
And of course, French Cuffs--and those cuff studs left little 1/16" pock marks all over the face of the guitar behind the stop tailpiece. In many places, the finish had flaked off.
For such a new guitar, it truly was in horrible condition, though it played and sounded great. I couldn't get past the cosmetics though, and passed on the deal with no regrets.
