Does the Discumbobulator (and, indeed, the other Emma pedals) run off batteries? I know various people who like the Q-tron sound better than the mini Q-tron (or maybe this is just an attempt to justify the higher price they paid ;)), but I've always leaned towards the mini Q-tron largely because I want something I can run anywhere off a battery without worrying about the flavour of electricity coming out of the wall.
The mini Q-tron is, of course, also way cheaper than the likes of the Discumbobulator :), but I don't buy piles of pedals (anymore ;)) and would probably pay more for the thing that was really gonna fit the bill.
