Here's the board I'm looking at: What I'm looking to do is add an AMZ-style mids-control. I kinda get the basic theory behind it, but I'm not sure where it goes in my particular circuit, nor am I 100% sure how it is supposed to look. Also, the 25k pot, how does that get wired in series? Does the 3.3k resistor attach to 2 ends of the pot, or what? Help me out, please!
