Tusq is awesome, I’ve replaced a few Les Paul nuts with their precut replacements. String spacing was a dead on match for the stock nut. Just had to file the bottom down evenly to get the height to match. Old nut comes out easy too. Just used a razor to gently cut the clear coat so it wouldn’t tear, then just tapped the old one with a small rubber hammer and it fell right out. One or two tiny dabs of glue on the bottom of the new one (want to hold it in place, not permanently glue it in in case it ever needs to be replaced) and it’s good to go. Recently though I’ve just used those Stewmac nut files to just clean up the existing nut, then sprinkle some graphite in the slots. That works just as well for tuning stability and is way easier.
