I've now received my Twin Earth pedal. I like it a lot, but there is some loss of low end. However, I compensate for this with the clean signal mixed in with a Boss LS-2. I've only used it at home, so I've no idea whether this would work in a band situation. It is I believe like a muff (although I could be wrong), but has a harsher fuzz at the more extreme settings. The alpha omega switch is supposed to change from retro to modern fuzz, but both sound pretty similar to me. The chaos setting is fun, mad and chaotic, but I'm not sure you would ever use it, as this setting makes a real racket without actually playing anything. Overall, a great pedal if you like noise and want something a bit different. Best of all its British, relatively cheap and I have done my bit to support what little British Industry we have left.
