I haven't owned a TS before (I know, where have I been ) so have no ability to say how accurate it is from a copy point of view.
What I can say is that it's a decently put together pedal that sounds pretty impressive - the impressiveness goes up when you remember the price. I prefer it with the gain down fairly low and it then makes a wonderful 'almost clean' boost.
The knobs are butt-ugly but other than that the quality of finish on the one here is just fine.
The instructions have been fairly poorly translated from the Chinese - no idea why they wouldn't send them to a Brit to proof read prior to printing rather than just Babelfishing it and hoping for the best.... For example
LED will be in red light when the effect pedal in use. If no light or in the dim light, please change new battery
That is nitpicking, though..... It amazes me how someone in China can build this and stick it in a box to a re-seller over here who can sell to Amazon who can give Royal Mail a few bob to deliver it and everyone still makes money out of £30.... It just does not compute. Even has a battery in it.
