I can’t remember the name of the one I have. It’s similar to this style, but the posts are changeable from 1-3.5mm. I will say, Clapton is easier to wind than that tiny round wire- at least I think so- but nothing is weirder than winding flat. I cannot get a coil that doesn’t look like a freak show with flat.
Watched the video a couple months back and tried doing the coils myself.
Couldn't get them turns all lined up,they were always overlapping each other,after about 2 meters of wire wasted i called it a day,put them thingys in the box and for the sake of my mental stability forgot they ever existed.
