I'm trying to get a better inderstanding about the differences between these two styles and how they actually work. From what i've read a cathode follower has less insertion loss(which I assume means it sends less signal to ground when the controls are on 0) which means it sends a stronger signal(gain) to the output section. Technically speaking, why does it work this way? A plate fed tone stack has more insertion loss because it sends more signal to ground, in effect decreasing the gain. This is why when you put the tone controls on 0 in a blackface fender you don't get much sound at all. Why does this happen? Do these different style tone controls affect the frequency response at all or simply the insertion loss?
