Not much to show for this, though I spent countless hours on the electronics over the weekend. It just wasn't working right, and lots of checking back and forth with the ohmmeter. Turns out the active EQ only works with one volume control. I really want separate volume control of the 3 necks, so I have to abandon the active EQ. Since I have 6 holes, I'll be going for the "standard" volume and tone for each neck. Found all the parts I need, but didn't get to install them yet.
