Since the pickup segments are all identical, having two reverse-P pickups in the middle would certainly be possible. But that's not in the works*. The plan is to have three individual volume controls, a 6-position Turnstyle switch, and a master volume and tone control. As with my other three pickup bass, one Turnstyle position will be manual control of each pickup, and the rest will be tone presets, each one giving the bass a different voice.
This one will also have a stereo option. When the second cord is plugged in, each of the tone presets will split the bass output -- E & A strings out the primary jack, D & G strings out the stereo jack. That's going to allow for some mind-blowing sonic possibilities! (The manual setting will send the same full signal out both jacks.)
*I'm not a believer in reverse-P. It's as legitimate as any other pickup arrangement, but I don't see the advantage. I know people who advocate it would say that the normal P pickup makes the already thin sound of the D & G strings even thinner, and that reversing the pickup compensates for that. My counter argument is that most of the time people play way up the neck, they're playing on the D & G strings, and most of the time when they're playing on the E & A strings, they're playing down the neck -- meaning that the majority of the time, the way the P pickup is normally situated, the segments are in proportionally similar positions relative to the strings they serve.
But all of that is predicated on the idea that pickup position matters a lot more than I believe it really does. I know I'm in what is probably a distinct minority with this opinion, but that's OK. People don't have to agree with me.
By the way, this is what it's going to look like with the neck.
