I acquired this guitar about six months ago. The frets are noticeably shorter/lower than my other guitars. I don't know how short because measuring that is kind of hard and I don't want to take the strings off. Is it likely that the frets were sanded down, or did these models come with short frets? The guitar is completely playable, and I can see why someone may prefer the shorter frets. I may want to sell the guitar, and I want to represent it accurately. Thanks!
