I think often the nib frets start sloping to the edge of the board too soon, I’m not sure why but possibly it has something to do with matching the height of the binding used, idk. I have a 2011 Goldtop 150. It has the nibs and it was pretty atrocious how bad the fret work was when I bought it. It was used, less than a year old but it probably was never played and I’m sure the fretwork was from the factory. I leveled the frets and crowned them. Then did it again about four years later and then again probably four years after that. Now it is about four years later again and the frets are low and it is time for new frets. This is my main guitar and it gets a lot of play time and I bend quite a bit so the frets get worn fast. While I do love the look of the nibs they are going bye bye with a new fret job. I’ve had other nib guitars and I have eliminated the nibs on them with new frets too. I prefer the frets to go to the edge. I’m going to do it this winter during a low gig window and after I’ve retiled my backsplash (or risk some serious trouble for putting it off for another guitar/amp project!).
