I'm considering swapping out the single coil pickup in my Squier Bronco for a dual rail humbucker. This pickup presents a number of wiring options, as covered in this article: Mod Garage: Four Ways to Configure a 4-Conductor Humbucker | Premier Guitar So, if I forego any switching, I would hook it up in the default mode with both coils connected in series. Simple. Tone variation is explicitly dependent on the capacitor and tone knob. If I introduce a push-pull pot, I would have one of 3 additional options: Both coils in parallel Split the south coil Split the north coil Question 1 - Are any of these variations useful on a Bronco bass? Question 2 - Does a combination (stacked) potentiometer/multi-position switch exist that would allow me to select between all 4 variations? Question 3 - If such a device as above exists, is it worth the added complexity? I'm hoping someone has already researched this and has some real-world conclusions.
