Dingwalls have varying knob sizes. For example, I think on a Z3, the pickup selector is a 1/4" shaft and the other four knobs are a 6mm shaft. The web site may have the details. I could have it backwards. You can use a brass shim sleeve if needed to fit a bigger knob on a smaller shaft.Each knob needs to be correct for the pot shaft it’s mounting onto, so a stacked pot will have 2 different shaft sizes.
Beyond that; there really aren’t any rules
