@jkahn I have a custom built guitar that has both an electric pickup (lipstick) and a traditional piezo pickup. To use the electric pickup I have to fit nickel strings and it has two separate circuits so when the Cole Clark tour came around to the exact guitar with the humbucker you mentioned, I paid extra attention. With mine the expectation is one would use one circuit or the other.
What they’ve done is a fair bit different to mine. (Mine is just two separate circuits). Theirs uses patent pending technology to allow their humbucker to be used with normal acoustic / bronze strings and have both circuits feeding into an amp at the same time. Or two different amps.
