I've got to tell ya... I really love my NAU Engineering amp. It has a Super Reverb sounding clean channel, and a Marshall/Modern high gain channel. Then there's a "bonus switch" that rolls back the gain on channel 2 to give that break-up sound. All great tones. I am really hooked on the versatility. So what's your favorite channel switcher, ones that you like AT LEAST TWO channel choices (I've seen many who like the clean channel but are so-so on the gain channel, so those don't count).
