"Oh yeah, I mean, it wasn't a very good guitar, most good guitars have got thrust rods in the necks that you can adjust or that'll keep them in shape, you know keep them straight. This one just, well it turned into a bow and arrow after a couple of months"

This quote by Eric Clapton is referring to the quality of a guitar he had. He is stating that the guitar was not very good because it did not have a truss rod in the neck, which is a steel rod that helps maintain the neck of the guitar right. Without this pole, the neck of the guitar can come to be warped gradually, which is what happened to Clapton's guitar. He says that it "became a bow and arrow after a couple of months," meaning that the neck of the guitar had become so warped that it was no more playable. This quote serves as a suggestion that high quality instruments are important for musicians, as they will certainly last longer and provide a better having fun experience.
