Both the pickups are working now, after I sorted things out in the control cavity. Great pickups, nicely rounded tone with great articulation and note bloom (I actually don't know what note bloom is. It sure sounds cool though!). Even with the tone controls turned all the way down, both pickups still have great clarity without even a hint of muddiness. They overdrive well, and although they seem to feedback a little bit easier than most of my other guitars, it's not anything that I would consider a real problem. Overall I'm very happy with these pickups, and would definitely buy another set in the future, if I have need of another set. Sin pickups gets a big "Thumbs Up" from me!
