Re: qp + jb
I had a JB combined with a QP in both the neck and middle of my Genny at first. The QP definitely is stronger than the JB, but it was still a nice sound. I opted to change the JB for a C5 which I like better. The QP still is stronger than the C5, but its a closer match. I use "tapped" QP's though, so I can morph them into a more classic single-coil tone.
The QP's are great pups, but I do prefer the versatility of having them tapped.
