I installed the Graph Tech Nut on my Ibanez GIO, replacing the mediocre plastic nut on said guitar. Installation was relatively easy, I had to file away a bit of material to install the nut. The resulting dust gets everywhere, so best do that close to a bin or in a workshop, not on your desk. Also, while filing, it smelled rather bad, kind of like a mixture of hot tar and gasoline. After filing the nut to the necessary height and installing it, tuning stability improved massively, and the tone of the guitar became less tinny. A small, easy mod with great effect. Would definetely recommend the Graph Tech nut as a replacement for the standard plastic nuts on most guitars.
