Thanks Brian!
The look I'm looking for is akin to the 7vwh's I have. I can't really tell what material is used for the stem there, it looks like some sort of wood, but I'm not sure. Very light colored with little tiny stripes on the material.
It's also very thin. I can see on one neck, they used a much wider routerbit and a lot of filler, but on another there's almost no filler. I wonder what kind of routerbit they used, it's just a few mm.
