I thought I knew a lot about pots. I had pretty good electronics training in the Air Force but the Air Force doesn't use pots for volume or tone. In order to learn I have been checking out websites (Seymour Duncan, StewMac, CTS, etc.) and they seem to be an excellent source of information. My problem is that they may be too good. I think I am suffering from information overload. I'm not as confused as I was when I started but I still have not answered the questions I had when I began. I'm trying to discern the difference between volume and tone pots. Yes, I have found that they are mechanically the same but wired differently. That only brings up new questions: 1. Does wired differently mean that they are somehow wired differently internally or by the connections that they use externally? I realize that volume pots use three connections and tone pots use two but that makes me think that they are different on the inside. 2. I have learned that tone pots are designated "A" and volume pots are designated "B". This different designation would, again, make me think there is an internal difference between the two. When I look at product descriptions on these websites all they show is "control" pots. I have yet to see any designated either "A" or"B".
