I just bought a used Ibanez that sounds and plays very nice but it has a good bit of fret wear on the 1st, 2nd, and 3rd frets. I think the previous owner never played past the 3rd fret. Due to the wear it buzzes a bit on the low E and A strings until you play above the 3rd fret, then it's fine. The rest of the neck has no fret wear at all. I've never shied away from doing any type of repair but this is one I've never done. I need to replace those three frets. Is this a do-able job for a do it yourselfer?
