I made a series of reversible changes to my Fender American Standard Stratocaster because despite the passage in two makers, the problems (buzz) persisted.
I changed the Nut, the guide ropes and bridges.
This opinion concerns the Nut "Graph Tech Nut" graphite with pre-cut notches, not the room white Tusq shown above.
Replacement Nut was an operation which I found very difficult. We had to remove the original part and then scratch the surface of my maple neck using a sharp knife and use a screwdriver to lift the nut end. Fortunately, everything went well with no damage.
The play Graph Tech has a pin that I had to file because there is no corresponding hole on the sleeve of my Start. The curvature of the saddle is not exactly the handle and I had a little sand to reduce the width. Then I could fix the saddle again by adding a drop of glue in the middle. Nothing insurmountable, but work fine anyway.
I use a set of string slightly thicker than the grooves of the nut, ideally, should therefore expand a little nicks, but I have no problem and most importantly, this change in addition to replacing the original bridges will be removed the buzz.
The guitar is finally set properly, without noise and is more enjoyable to play.
It is a good modification to do with caution, however, and we must find the right piece for the handle because there are many models from Graph Tech. The one I bought was probably not ideal for gutiare.
