Yeah, it seems to me the faded-denim look from PRS depends heavily on the underlying specimen of lumber, which can vary widely in tendency to soak up the dye, and also how hard the finishing technician bears down with the sander after the dye is applied. The process itself is simple - dye, sand back, dye some more - but getting the color concentration right, and more particularly, getting it to YOUR vision of what the faded denim should look like - is the tough part.
