In one of the first Microrack videos I can see a variety of potentiometers on what I presume were prototypes.
Ignoring the one with the red cover, the filter module has ones with white marks on them rather than just indentations. These make it much easier to see the position/value set on the pot. I painted mine with a tiny bit of white paint recently to make them visible in some videos I made. Are there any plans for the ones with white marks to make a come back?
