I can understand why they do that with Squiers but I've never understood why they do that with Fender-branded guitars, especially trem-equipped ones. That's my favorite part of the Speedloader on my Floyd: all metal nut. Will never ever wear out or bind a string. My Showmaster thankfully came with a graphite nut.

That's one thing that impressed me about the Agile AL-3000s I was looking at. All of them come with a Tusq nut AND a graphite one in case you prefer that. Why Agile can do that and not Fender is beyond me.
