This is a great nut and was exactly the right size for my Jazzmaster neck. Like the other reviews, I had to drill six small holes to accommodate the screws in order to lower the action. But a plus side of the holes is that they act as an anchor point to hold the nut in place, and for me they were easy to make.
Anyway, if you're confident enough to be changing the nut on a guitar you're probably skilled enough to make the necessary adjustments.
I really like this nut, and it looks great too! Definitely worth every penny (and top service from Thomann as always).
