Great Idea, But Not Executed Properly

So let me start with this: I’m a luthier, a session guitar player and I’ve built many guitars over the years. I’ve carved too many guitar nuts to even try to count them all. I was excited when I stumbled across the Guyker Adjustable Brass Guitar Nut. I thought, "now this is a great idea!" To able to adjust the nut height for different players or different setups without having to carve a new nut every time. This could be amazing.

Guyker almost got it right. I realize that most guitars will need to be modified for this brass nut to work properly. So I did what needed to be done to give this idea a fair shot. And I will say, it is cool. But there are a few problems. 1. The tolerance in the threads of the adjustment screws and the nut itself are not right. The threads need to be much tighter to have a consistent result and proper intonation.. There’s simply too much “play” in the threads. The zero point of each screw head where the string makes its exit of the nut is inconsistent from string to string, and can actually move around when the string it tuned or bent during playing. This affects both intonation and transferring of string energy and resonance into the neck itself.

2. On both fender guitars I tried, the screws are too long and end up hitting the bottom of the nut slot and the nut slot needed to be filed down more to make them able to get low enough for the desired nut height.

3. On all of my les Pauls, the Guyker Adjustable Brass Nut was just simply too tall. I would either have to file off the bottom of the brass nut itself to make it sit at the proper height, or file a lot of wood out of the nut slot itself. Filing too much would out of the nut slot worries me. What if I need to put a traditional nut back in? Or what if it weakens the Integriy of the guitar in that area of the neck?

I feel like Guyker is onto something here. But I think the execution needs some more refinement.
