Reloved Guitars 'custom adjustable Tusq nut' - rationale

This video explains how I use the Tusq 'adjustable nut' insert in a custom upgrade for my set up customers and, more importantly, why I make this modification.
As soon as I saw Graph Tec making this nut I realised I could use it for my own purposes and fitted it to all my 3-tuners-a-side guitars, one after another. It's THAT good. I wouldn't go back - so much so that these days I also modify regular Tusq nuts for Strats and Teles with grub screws to make them adjustable too.
