Well, Series pickups and electronics showed up at the Alembic forum almost the same day, so I snapped them up. They are both very old, original PF-6 and butterscotch colored pickups with single screw tabs. I'm going to try putting the humcancelling pickup inside the bass to start off with to see if I can avoid routing out the bass further. I'm going to wire it as a Series II. Pickups first into a ACG preamp to see how that is while I rebuild the electronics to fit the bass. I still need to round up a few parts (pickup selector switch, CVQ pots) and make sure everything is functioning. I'm also considering building a copper box for the inside of the bass as Alembic did for Starfire mods back in the day to get good shielding.
It's exciting!
