Physically there is nothing wrong with this pedal.
It is solid and sturdy. I love the big nobs.
The sound is good, and it comes very close to my old Boss DF1, but still have a little darker sound to it.
BUT, the big problem here is the noise. I don't know if it is just me who have been unlucky to get the one pedal that make noise, or they all do it. I don't have a noise filter yet in my chain, that might help. But when I turn it on it buzz like crazy, like nothing I ever heard before, and so loud. I have two other pedals from TC from the same series, and they make no noise at all. And I have two other distortion pedals who does not make any noise. So I take away two stars because off the noise.
