I've seen these knocking about for a while and never took much notice as I thought they were cheapo copies of famous effects, anyway it turns out that although they are pretty much copies of Tubescreamers, MXR Phase 90s etc, they are all true bypass and use high quality op-amps and tantalum caps etc.
I'm considering a few of them as they're about the same price as Boss pedals. I found some sound clips, they do seem a bit bright but I think the guy used a strat into a jcm900, and they're mp3s so thats no surprise.
The
Japanese site has most clips but the Distortion M isn't labelled but does work, just click on the speakers. The
English site is easier to understand but doesn't have the clips of the backing and the solo playing together.
