I have never owned a guitar that has the option to put a humbucker in parallel mode. How useful is it? What about having just the inner coils in parallel? The specifics I'm asking about: Agile Pendulum 92528 with the Cepheus Rail pick-ups. I have the option of running it into a balanced input. I like balanced signal cables/inputs. So the thought is to run the four coils into a 4-way selector that will give me: Neck|Outer|Inner|Bridge balanced-out. If I do, they're essentially fixed as series. I'm thinking that if I'm going to re-wire the guitar, maybe I should wire-in a series/parallel switch instead of going balanced.
