Doing some research on the new Epi line for 2020.

It states"The control assembly features the treble bleed circuit to keep your highs sparkling when turning your volume down, 3 push-pull pots to switch between the humbucker and the single-coil sounds, and phase switching for the most versatile and sonic variety. "
Forgive the ignorance. I have never played or had a guitar that had a treble bleed circuit and phase switching. I get the push pull pots. Maybe someone can enlighten me on those functions and their benefits and are they that needed or necessary. Thanks
