There were 2 selling on the forums too. From what I have heard, they are awesome at what they do. I had their Dark Echo pedal and loved it. The build quality and circuit design are also works of art. I would be all over one if I needed a mod pedal.
It's exceptional for what it does and the build quality is stunning. However, I'm having difficulty dialing in a chorus I like and recently, I've been looking at a Cmatmods unit as a replacement. I just don't need a lot of sounds the Mod Zero is capable of creating.
