I used to question it too. In fact I preferred my Mark III Boogie over the Mark IV for precisely that reason, too many knobs on the Mark IV which I didn't think were necessary.
Admittedly, I don't change tones much during songs, and when I do, I usually accomplish it with my pedal board. But I certainly do mess with my guitar's settings in between songs as different songs often call for a different tone. I have found a few settings that I usually go to. The versatility of the on-board electronics then comes in handy for subtle tweaking to compensate for little differences from such things as the acoustics of the room I'm playing in, how new/old my strings are, even things like humidity and temp.
It's like I'm constantly telling my 9 year old: the difference between easy and hard is knowledge and practice. When you are first exposed to anything new, be it math, a new gameboy game, a new sport, whatever, it is hard. Once you learn about it and practice, it is easy. The same with Alembic electronics. I admittedly struggled at first with my Electrum. Now it's definitely much easier and the controls make a lot more sense. The same with my SF-2. Last night at rehearsal I felt I broke though a wall and really grokked it for the first time.
Sure, my Fender is more basic and easier to adjust on the fly. And when I want to sound like a Strat it does the job brilliantly. But it is very limited compared to the Electrum and just doesn't get the incredible presence that the Alembic has. Remember, just because the ALembic has more controls, doesn't mean you have to touch every one on every song. It's all about possibilities.
