As a reference:
My Lakland I sold was 2 pup active/passive. With it I had 4 knobs and 1 switch. The switch controlled active passive. The knobs were vol, blend, and 2 concentric knobs: 1 handling treble and bass, the other mid and mid freq.
My Dingwall is 3 pup active/passive with 5 knob 1 switch. The switch is active/passive. I knob is vol, another a rotary pup selector (bridge, bridge middle in series, bridge middle in parallel, and neck), the remaining 3 are treble, middle, bass.
My Stingray is active only with 1 pup. 3 knob. Vol, treble and bass.
All the others are passive only.
