Seems sort of convoluted, and in reality it only has pickups in two locations. My Godin Shifter came with three pickups and six switching options. In theory you could wire it ala Brian May with an on/off and a phase flip for each pickup. I'm busy improving the bass in other areas, but the notion of having that much control is interesting. The difference with the Godin is that there is a pickup butted up against the neck, and one right down at the bridge as well as the conventional P-bass location. The Fernandes in OP's looks like a Jazz on steroids. The pickups are in the Jazz location and you can switch on or off each coil for each pickup. Quite a cool setup, and probably good for getting many Jazz tones old and new. No option for series/parallel for the pickups or the individual coils.
