I recently purchased used a PRS SE 245 Soapbox for a nice price. The neck was very straight and it plays really good. However, I kept hearing a little wierd buzzing that I didn't like so I put the right amount of relief in and now it is worse. The lower strings fret out when I try to bend them. I realized after closer inspection that the last two frets have come up out of the fretboard a little. What would be the quickest way to fix this? I really can't even reach these frets so I've thought about just pulling them out. I did try to hammer them in but they didn't budge. Maybe I should just sand them down?
