Digitech Bad Monkey
I think this proves the monkey theory. There's obviously nothing that makes it externally or tonally monkey-ish, so it's obviously called that because the Monkey inside gets very angry and tears up your singal instead of delaying.
So Bad Monkeys are all the Delays/Octave/Chorus(lots of Baby Monkeys playing slightly out of tune) pedals where the Monkeys which to rebel against their function and do exactly the same thing, because they know no other way of doing so.
As a side note, I tried a Bad Monkey and it was actually an awesome overdrive for a "Digital" pedal. One of my favourites I've heard, actually. Might pick it up some day.
