"Oh my!!! How did they do it? How did they get that incredible Q-Tron envelope follower sound into such an inexpensive battery-operated unit? How did they manage to create an envelope follower that's as smooth as a baby's bottom at every combination of settings? You know what, I don't care, just give me the damn thing!"
