I just checked out the ZVex Lo-fi loop junky pedal demo video and it looked really cool, don't know what I'd do with one, but... Anyway, what really excited me was the vibrato of the unit. I realized that it might be cool to have a vibrato on my pedal board. Who does a good one? What's "the best"? Does anyone sound similar to the one on the ZVex pedal? I have no clue about vibrato pedals cause I have just checked out different dirt boxes for ages..
