Since I don’t have any pickups with a coil tap, I can only respond regarding coil splitting, which I use all the time for a variety of reasons. And it’s way more than a volume reduction, but you have to explore with an open mind. Split = Clarity = articulation and that’s something I need regularly and can get from splitting. It also offers some phasing change when combined with another pickup, which is another great option. We’re talking art here, which embraces the different/uncommon/weird.
