I recently finished building my first bass, which I love and has become my #1 bass. I have an Ibanez that is now my #2. I was thinking about upgrading the Ibanez for a while but never had time, now that it's #2, I still want to upgrade it and its not a big deal if its out of commission for a while. My question is, being a complete n00b with active pickups, does this set (http://www.bestbassgear.com/emg-pickups-pj-bass.htm) come with everything I need to switch from passive to active? What else would I need to do/get?
