Man, you are talking way over my head there. Phase correction? All I know is that the Morley is user-friendly. It has no noise when you switch. It does not affect tone. Just so happens I was monkeying with my Morley today. The power of playing through two amps spread out in my music room is a cool trip. I was also monkeying with my BOSS footswitch. If you don't have one of these, I'd suggest one. Great investment. Can turn things on and off cleanly, silently, easily. This one is also unlatch. Can do a momentary on or off.
