Take a look at this pedal, tons of delay, reverb and a looper. I watched several videos on it where it was up against a bunch of the big names and it either sounded just as good or better. In every case it had way more ability than the others. The biggest thing was it is $250 vs. $500 - $600! If you need a real good delay / reverb, and don't have a looper yet, man look no further. I guess the older one was very well liked, but this one can do a lot more including midi and it can be used with a mic. There are a bunch of videos on it if your interested one.
