This gives me the chance to toss some fun content into a reply! This is here for reference and not an effort to get you to change your mind. Your comment contains two hotly debated topics with guitarists. First, the word 'pick guard' is a bit of a misnomer. The finish on (most) guitars is harder than a plastic pick and the scratches are generally understood to have been done with fingernails - more so than anything else. It is generally seen as fact and science-based and we still call 'em pick guards. In flamenco (and a very small amount of classical) there's golpe, which is to use your finger and knock on the guitar. There's then a golpeadore, which is usually a very thin piece of sticky, clear plastic that is to protect the finish. Second, and this one is not factual but very subjective, what good is a guitar that you can't play? I have guitars that I think are too valuable to be played frequently but other people will argue and say that a guitar that isn't played is a useless guitar. They generally make exceptions for museum pieces and guitars that are known to be fragile. But, people like to argue this one back and forth. I don't own a harp guitar. I probably should. I don't do much composition and there's not much call for a harp guitar in covers. There are no popular songs, that I know of, that were originally recorded with a harp guitar.
